Modelling transport processes in stellar radiative interiors

open access: yesEPJ Web of Conferences, 2015
I report here on the different transport processes redistributing angular momentum and nuclides in stellar radiative interiors and on their modelling in stellar evolution codes.

Asteroseismology of Close Binary Stars: Tides and Mass Transfer

open access: yesFrontiers in Astronomy and Space Sciences, 2021
The study of stellar oscillations allows us to infer the properties of stellar interiors. Meanwhile, fundamental parameters such as mass and radius can be obtained by studying stars in binary systems. The synergy between binarity and asteroseismology can

Solar-Like Oscillators in the Kepler Era: A Review

open access: yesFrontiers in Astronomy and Space Sciences, 2021
Many late-type stars across the Milky Way exhibit observable pulsations similar to our Sun that open up a window into stellar interiors. The NASA Kepler mission, a space-based photometric telescope, measured the micro-magnitude luminosity fluctuations ...

A Semirelativistic Equation of State for Stellar Interiors [PDF]

open access: yesContributions to Plasma Physics, 1999
AbstractUsing the technique of Padé Approximants for the correlation contributions of charged particles we are able to reproduce complex mathematical expressions by simple algebraic formulas. The Padé formulas are analytical expressions, which interpolate between certain density‐temperature regions and are characterized by exact asymptotics. We present

Turbulence and nuclear reactions in 3D hydrodynamics simulations of massive stars [PDF]

open access: yesEPJ Web of Conferences, 2023
Our knowledge of massive star evolution and nucleosynthesis is limited by uncertainties related to multi-dimensional processes taking place in stellar interiors.

Turbulence in Stellar Interiors [PDF]

open access: yesInternational Astronomical Union Colloquium, 1993
AbstractThis review focusses on the most recent work which has been achieved concerning turbulence in stellar interiors. Among all possible causes for such turbulence, the most powerful is certainly the convective instability in unstably stratified regions, but little was known until now beyond the fact that thermal convection is capable of ...

White-Dwarf Asteroseismology With the Kepler Space Telescope

open access: yesFrontiers in Astronomy and Space Sciences, 2020
In the course of their evolution, white-dwarf stars go through at least one phase of variability in which the global pulsations they undergo allow astronomers to peer into their interiors, making it possible to shed light on their deep inner structure ...

The Power of Asteroseismology for Early Stellar Evolution

open access: yesFrontiers in Astronomy and Space Sciences, 2019
Stars are the building blocks of planetary systems, clusters, associations, and galaxies. The evolution of stars is driven by physical processes in their interiors making theory of stellar interior structure and evolution an important ingredient of ...

Unveiling the Structure and Dynamics of Red Giants With Asteroseismology

open access: yesFrontiers in Astronomy and Space Sciences, 2020
The Kepler mission observed many thousands of red giants. The long time series, some as long as the mission itself, have allowed us to study red giants with unprecedented detail. Given that red giants are intrinsically luminous, and hence can be observed

Recent advances in modeling stellar interiors [PDF]

open access: yesAstrophysics and Space Science, 2010
Advances in stellar interior modeling are being driven by new data from large-scale surveys and high-precision photometric and spectroscopic observations. Here we focus on single stars in normal evolutionary phases; we will not discuss the many advances in modeling star formation, interacting binaries, supernovae, or neutron stars. We review briefly: 1)
