GAIA AND PHYSICS OF STELLAR INTERIORS [PDF]

EAS Publications Series, 2002
Understanding the stellar interiors is an important issue for astrophysics, but also for fundamental physics. The physical description of the stellar material implies statistical physics as well as hydrodynamics. We give examples of unsolved physical problems and their consequences for predictions of stellar properties and evolution.

Stellar Physics at Dome C [PDF]

EAS Publications Series, 2005
We present a short synthetic summary of prospects for stellar astrophysics from Dome C. We conclude that a progressive strategy could be defined, giving access to a 2 m-class telescope, equipped with a highly efficient optical/infrared spectrograph/spectropolarimeter and a wide-field infrared imager, in the 2008 timeframe, then ...

Physics optimization of stellarators

Physics of Fluids B: Plasma Physics, 1992
The theoretical and experimental development of stellarators has removed some of the specific deficiencies of this configuration, viz., the limitations in β, the high neoclassical transport, and the low collisionless confinement of α particles. These optimized stellarators can best be realized with a modular coil system.

Physics of Stellar Convection

AIP Conference Proceedings, 2009
We review recent progress using numerical simulations as a testbed for development of a theory of stellar convection, much as envisaged by John von Newmann. Necessary features of the theory, non‐locality and fluctuations, are illustrated by computer movies.

Physics of compact stellarators

Physics of Plasmas, 1999
Recent progress in the theoretical understanding and design of compact stellarators is described. Hybrid devices, which depart from canonical stellarators by deriving benefits from the bootstrap current which flows at finite beta, comprise a class of low aspect ratio A<4 stellarators.

A physical model for the stellar IMF

AIP Conference Proceedings, 1997
We propose that the stellar initial mass function (IMF) arises as a consequence of the existence of random supersonic flows in molecular clouds. A Miller-Scalo like IMF is predicted for the typical physical conditions in molecular clouds, and a more “massive” one in star bursts.
