- From the double pulsar to magnetars: Observational constraints for neutron-star magnetospheres du 20 octobre 2008 — Michael Kramer
The talk reviews the basic emission properties of pulsars and aims at finding a particular set of characteristics that is able to constrain relevant emission theories. This is done by contrasting the properties of normal pulsars, millisecond pulsars, and also magnetars. Some unexpected lessons can also be learnt from systems like the Double Pulsar. The talk prepares the discussion of possible theoretical explanations to be presented in the following talk.

- Theory of pulsar magnetosphere: From radio to high-energy pulsed emission du 20 octobre 2008 — Jérôme Pétri
Although discovered 40 years ago, pulsars remain astrophysical objects of enigmatic behavior. We can summarize our current theoretical knowledge by saying that they are strongly-magnetized rotating neutron stars (Michel, 1991). To date, indeed, no self-consistent model is able to either predict their observed emission spectrum or explain the acceleration and radiation (from radio to high-energy gamma-ray) mechanism of particles. Nevertheless, an important effort towards modeling the pulsar magnetosphere seems to provide a satisfactory picture of what a pulsar is.
To begin with, I will briefly review the main observational facts about pulsar emission properties. I will then expose the different existing models able to describe pulsed radiation from radio frequencies up to high-energy gamma-rays. Finally, I will discuss in detail an alternative scenario accounting for the production of high-energy pulsed emission, which is related to a peculiar structure called striped wind, whose geometrical configuration is very similar to the solar wind (Coroniti, 1990; Michel, 1994; Bogovalov, 1999). I will show that the polarization of the synchrotron emission emanating from such a geometry is in agreement with recent optical observations from the Crab pulsar (Pétri & Kirk, 2005).
Extrapolating to the highest energies through inverse Compton scattering, I compute and reproduce the light curves and phase-resolved spectral variability of some gamma-ray pulsars. Indeed, with the help of the striped wind model, I can fit observations above 10 MeV for the Vela and Geminga pulsars (Fierro et al. 1998). The recent launch of the GLAST satellite, working between 20 MeV and 300 GeV, will allow a detailed study of the gamma-ray radiation and therefore of the acceleration process in a pulsar magnetosphere. Eventually, a discrimination between the proposed models will be possible.

- Détection des planètes extra-solaires par émission d’ondes radio du 24 novembre 2008 — Philippe Zarka
Planet-star plasma interaction can be described as the interaction of a plasma flow with an obstacle, each being possibly magnetized. Examples of the four possible situations are found in our Solar system, with an intense radio emission being produced in three cases out of four, when either the flow or the obstacle is strongly magnetized. Scaling laws are derived which relate the emitted radio power to that dissipated in the various corresponding flow-obstacle interactions. They are generalized as a "radio-magnetic" scaling law between the output radio power and the magnetic energy flux convected onto the obstacle.
Extrapolating to the case of exoplanets, we find that hot Jupiters may produce a very intense radio emission due to planetary magnetospheric interaction with a strong stellar wind, reconnection between planetary and stellar magnetic fields, or unipolar interaction between the planet and a magnetic star (or strongly magnetized regions of the stellar surface). The emitted radio power is expected in the hecto-decameter range with intensities 1E3 to 1E6 times that of Jupiter (unless some "saturation" mechanism is at work). Corresponding flux densities should be detectable at the ten-parsec range with modern radio arrays. We briefly discuss ongoing observational searches as well as the interests of direct radio detection.

- Théorie des émissions radio planétaires du 24 novembre 2008 — Philippe Louarn
Parmi les diverses théories proposées pour la génération des ondes radio dans les régions aurorales (de haute latitude) des magnétosphères planétaires, seule celle de l’instabilité maser cyclotron rend compte de l’ensemble des
caractéristiques observées. Le fonctionnement de l’instabilité est ici décrit en détail et placé dans le contexte des magnétosphères planétaires : condition de résonance électron-onde et taux de croissance, critères d’instabilité, fonctions de distribution électronique instables comme source d’énergie, origine de ces distributions, lien avec les sous-orages, rôle de l’hétérogénéité
spatiale de la source, rôle d’une cavité de plasma comme région source, saturation de l’instabilité... Cette description est fondée sur les mesures in situ effectuées par les sondes spatiales circumterrestres comme Viking et FAST, et les résultats sont transposables aux émissions radio de Jupiter, Saturne et de toutes les planètes magnétisées.

- The magneto-spheric accretion onto young objects: An observational review du 2 février 2009 — Jérôme Bouvier
Young solar-type stars, the so-called T Tauri stars, possess strong and complex magnetic fields, whose strength and topology are now directly measured through spectropolarimetric techniques. These strong fields disrupt the inner accretion disk over a distance of a few stellar radii, thus leading to magnetic funnel flows connecting the inner edge of the disk to the stellar surface, to hot spots which are the signature of accretion shocks as the free-falling gas hits the stellar surface near the magnetic poles, and to an inner disk warp as the gas and dust in the inner disk are lifted up away from the central plane by the large-scale stellar magnetic field. I will provide a summary of the observational evidence available so far for strong magnetic fields in young stars, inner disk truncation, accretion funnel flows, accretion shocks, and associated outflows. I will also discuss the evidence for instabilities in these MHD process which are observed to be strongly variable on timescales ranging from a few hours to several years. Eventually, I will discuss the implications of magnetospheric accretion-ejection processes for the angular momentum evolution of young stars.

- The magneto-spheric accretion onto young objects: A theoretical review du 2 février 2009 — Claudio Zanni
In this talk I will review the main theoretical aspects concerning the interaction between the magnetosphere of a young forming star and a surrounding accretion disk. Nowadays, it is clear that young stars are magnetically active, having large-scale magnetic fields of a few kG. Such a field is strong and extensive enough to control the accretion onto the star and to play a crucial role in the regulation of the stellar angular momentum. In fact, one of the most puzzling aspects of low-mass protostars (so called T Tauri stars) is that they exhibit slow and constant rotation periods (3–10 days, well below their break-up speed) despite the fact that they are still actively accreting and contracting.
Referring to analytical and numerical arguments, I will first analyze the mechanism which leads to the truncation of the disk and the formation of accretion funnels onto the surface of the star. I will then elucidate different solutions to balance the stellar spin-up due to the accretion torque and to contraction. In order to evaluate their efficiency, I will show results of numerical MHD simulations and describe different interaction regimes between the magnetosphere and the accretion disk.

- Influence of turbulence and magnetic field on the star-formation process: An observational review du 3 avril 2009 — Philippe André
While gravity is believed to be the main player in the star formation process, turbulence and magnetic fields have been invoked to play a major role in regulating the star formation rate in giant molecular clouds. I review the properties of low-mass dense cores as derived from observations and discuss them in the context of the current debate between two extreme paradigms for the star/core formation process: the quasi-static, magnetic picture vs. the dynamic, turbulent picture.
Neither of these extreme scenarios can explain all observations. Pure ambipolar diffusion has relatively long growth times for typical ionization levels and has difficulty satisfying core lifetime constraints. It is also inconsistent with the relative mass-to-magnetic-flux ratio between core and envelope recently measured in a few cases through Zeeman observations. Purely hydrodynamic pictures have trouble accounting for the observed spatial distribution of cores and young stellar objects within cloud complexes and for the low velocity dispersion measured within and around individual cores. Furthermore, there is strong evidence from, e.g., polarization studies that the envelopes of nearby clouds such as Taurus and the Pipe Nebula are magnetically dominated. A possible favorable scenario is a mixed model involving gravitational fragmentation and MHD turbulence in molecular clouds close to magnetic criticality.

- Influence of turbulence and magnetic field on the star-formation process: A theoretical review du 3 avril 2009 — Ralf Klessen
Stars form by gravoturbulent fragmentation of interstellar gas clouds. The supersonic turbulence ubiquitously observed in Galactic molecular gas generates strong density fluctuations with gravity taking over in the densest and most massive regions. Collapse sets in to build up stars and star clusters.
Turbulence plays a dual role. On global scales it provides support, while at the same time it can promote local collapse. Stellar birth is thus intimately linked to the dynamical behavior of parental gas cloud, which governs when and where protostellar cores form, and how they contract and grow in mass via accretion from the surrounding cloud material to build up stars. The thermodynamic behavior of the star forming gas plays a crucial part in fragmentation and influences the stellar mass function as well as the dynamic properties of the nascent stellar cluster.
I will discuss our current understanding of molecular cloud formation in the disk of our Milky Way. In particular, I will focus on the characteristics of interstellar turbulence and on the effects of magnetic fields in star formation.

- Modèles MHD du noyau terrestre contraints par les observations récentes du champ magnétique terrestre – 1. Revue observationnelle du 22 juin 2009 — Alexandra Pais
Until very recently, the inversion of geomagnetic field models for core surface flows has been treated as a purely kinematic problem, using the core surface radial field as a passive tracer for the flow. We will review this classical approach and its main results. Recent satellite missions boosted an increasing complexity of computed magnetic-field models, where the separation of different contributing sources seems more and more realistic. Unfortunately we still have a blurred view of the magnetic field at the core-mantle boundary. This is an important issue as core flows are detected from the motion of magnetic flux lines leaving the Earth’s core. We will discuss the strategies that have been developped to fully account for this difficulty.
In an effort to use recent geomagnetic models to explore the Earth’s core dynamics, we have been testing geostrophic/quasi-geostrophic flows. To sustain the relevancy of these flows, we will argue that motions evolving on timescales shorter than the magnetic diffusion time are almost quasi-geostrophic and thus axially invariant: they are completely determined from a stream-function, which is independent of the z-coordinate along the rotation axis. We will then report how a planetary-scale anticyclonic gyre has been inferred within the Earth’s fluid core.
It is likely that magnetic fields are much stronger inside the core that at the core surface. The detection of a 6-yr periodicity in calculated core flows may be the signature of Alfvén waves propagating inside the core. That gives us an estimate of the magnetic-field intensity. We will introduce the data assimilation scheme that we are now using to further constrain the geometry of the magnetic field in the core interior.

- Les rayons cosmiques – 1. Revue observationelle du 2 novembre 2009 — Alexandre Marcowith
Cet exposé vise à une introduction au rayonnement cosmique sous ses aspects observationnels et phénoménologiques, et renvoie au second exposé qui traitera les aspects théoriques du sujet. Nous commencerons par un bref aperçu historique, puisque nous célébrerons bientôt le centenaire de la découverte du ce rayonnement. Nous aborderons ensuite les grands principes de la détection du rayonnement cosmique ; ceux-ci conjuguent des mesures directes par vols ballons ou missions satellitaires à basse énergie et des mesures indirectes au sol pour les plus hautes énergies. Nous évoquerons ensuite, brièvement, les observations dans les différentes longueurs d’onde et par les nouveaux messagers des sources astrophysiques. Une troisième partie sera consacrée à la phénoménologie du transport du rayonnement cosmique. Pour ce faire, nous utiliserons les résultats passés en revue dans la partie liée aux observations. Une fois le transport mieux connu, nous pourrons aborder les propriétés des sources. Enfin nous finirons cette revue par les dernières évolutions concernant le modèle standard du rayonnement cosmique galactique.
