Plasma Astrophysics: Kinetic Processes in Solar and Stellar Coronae, Second Edition [PDF]
A collision‐less plasma is an ionized fluid that is so hot and tenuous that interactions between individual particles are unimportant. In such a plasma, electric and magnetic fields mediate interactions among particles, and fundamental physics is addressed by kinetic theories that describe not only the spatial and temporal variations of the medium, but

Advances in Solar-Stellar Astrophysics [PDF]
The discovery on stars of coronae and of X-ray emission from flares in the 1970's opened up the investigation of stellar activity. Solar-stellar astrophysics has now become a two-way street. The rich detail of the Sun provides a close-up view of physical phenomena, while the stellar observations provide a way to, in effect, vary the otherwise fixed ...

Solar, Stellar and Galactic Connections Between Particle Physics and Astrophysics [PDF]
The very small and the very large are intimately connected in Nature. Particle physics and astrophysics meet in fundamental questions: the structure and evolution of stars; their end and how this is manifested; how we think galaxies are created from matter we have yet to discover and why we believe the most energetic particles cannot come from the ...

Simulations of stellar convection, pulsation and semiconvection [PDF]
We report on modelling in stellar astrophysics with the ANTARES code. First, we describe properties of turbulence in solar granulation as seen in high-resolution calculations.

Optimized gyrosynchrotron algorithms and fast codes [PDF]
Gyrosynchrotron (GS) emission of charged particles spiraling in magnetic fields plays an exceptionally important role in astrophysics. In particular, this mechanism makes a dominant contribution to the continuum solar and stellar radio emissions. However,

The HARPS search for southern extra-solar planets [PDF]
Context. Planetary companions of a fixed mass induce larger amplitude reflex motions around lower-mass stars, which helps make M dwarfs excellent targets for extra-solar planet searches. State of the art velocimeters with $\sim$1m/s stability can detect very low-mass planets out to the habitable zone of these stars.

The Role of Mixing in Astrophysics [PDF]
The role of hydrodynamic mixing in astrophysics is reviewed, emphasizing connections with laser physics experiments and inertial confinement fusion (ICF). Computer technology now allows two dimensional (2D) simulations, with complex microphysics, of stellar hydrodynamics and evolutionary sequences, and holds the promise for 3D.
