Simulations of stellar convection, pulsation and semiconvection [PDF]

, 2010
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]

, 2010
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,

Formation and Evolution of Planetary Systems in Presence of Highly Inclined Stellar Perturbers [PDF]

, 2011
The presence of highly eccentric extrasolar planets in binary stellar systems suggests that the Kozai effect has played an important role in shaping their dynamical architectures.

Nuclear Astrophysics [PDF]

, 1998
Nuclear astrophysics is that branch of astrophysics which helps understanding some of the many facets of the Universe through the knowledge of the microcosm of the atomic nucleus.

Modules for Experiments in Stellar Astrophysics (MESA)

, 2010
Stellar physics and evolution calculations enable a broad range of research in astrophysics. Modules for Experiments in Stellar Astrophysics (MESA) is a suite of open source libraries for a wide range of applications in computational stellar astrophysics.

NLTE modelling of integrated light spectra. Abundances of barium, magnesium, and manganese in a metal-poor globular cluster [PDF]

, 2019
We study the effects of non-local thermodynamic equilibrium (NLTE) on the abundance analysis of barium, magnesium, and manganese from integrated light spectroscopy, as typically applied to the analysis of extra-galactic star clusters and galaxies.

New Results on Standard Solar Models

, 2009
We describe the current status of solar modelling and focus on the problems originated with the introduction of solar abundance determinations with low CNO abundance values.

Solar, Stellar and Galactic Connections Between Particle Physics and Astrophysics [PDF]

, 2007
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 ...

Plasma Astrophysics: Kinetic Processes in Solar and Stellar Coronae, Second Edition

Eos, Transactions American Geophysical Union, 2003
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
