Basic Stellar Physics [PDF]

open access: diamondEPJ Web of Conferences, 2023
Polytropes, Virial theorem, evolutionary time scales, degrees of freedom, radiative transport, molecular weight, degeneracy, Jeans mass, and Eddington luminosity are basic ingredients to describe the physics of stars.

The physics of stellar interiors

open access: green, 1994
These are the slides for a seminar talk that I gave on August 9, 2022 as part of the Space Science and Security Summer Seminar Series at Lawrence Livermore National Laboratory. The talk gives an overview of some aspects of stellar hydrodynamics, and describes how realistic hydrodynamic simulations are used to improve stellar structure and evolution ...

Stellar turbulence and mode physics [PDF]

open access: yesAstrophysics and Space Science, 2009
An overview of selected topical problems on modelling oscillation properties in solar-like stars is presented. High-quality oscillation data from both space-borne intensity observations and ground-based spectroscopic measurements provide first tests of ...

Perspectives on the physics of late-type stars from beyond low earth orbit, the moon and mars [PDF]

open access: yesnpj Microgravity
With the new discoveries enabled thanks to the recent space missions, stellar physics is going through a revolution. However, these discoveries opened the door to many new questions that require more observations.

Stellar Physics and General Relativity

open access: hybridAstronomische Nachrichten
ABSTRACTThe general theory of relativity is currently established as the most precise theory of gravity supported by observations, and its application is diverse ranging from astronomy to cosmology, while its application to astrophysics has been restricted only to compact stars due to the assumption that the Newtonian approximation is sufficient for ...

Coronal dimmings and what they tell us about solar and stellar coronal mass ejections [PDF]

open access: yesLiving Reviews in Solar Physics
Coronal dimmings associated with coronal mass ejections (CMEs) from the Sun have gained much attention since the late 1990s when they were first observed in high-cadence imagery of the SOHO/EIT and Yohkoh/SXT instruments.

Stellar evolution and the Standard Solar Model [PDF]

open access: yesEPJ Web of Conferences, 2020
This contribution is meant as a very brief introduction to the principal concepts of stellar physics. First the main physical processes active in stellar structures will be shortly described, then the most important features during the stellar life-cycle

Toward a New Paradigm in the Analysis of Asteroseismic Lightcurves

open access: yesFrontiers in Astronomy and Space Sciences, 2020
This paper aims at being a provocative guide to the future of asteroseismology from the perspective of the analysis of time series, where the fundamentals of harmonic analysis are subjected to stress tests.
