Synthetic stellar populations: single stellar populations, stellar interior models and primordial protogalaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2004 We present a new set of stellar interior and synthesis models for predicting the integrated emission from stellar populations in star clusters and galaxies of arbitrary age and metallicity. This work differs from existing spectral synthesis codes in a number of important ways, namely (1) the incorporation of new stellar evolutionary tracks, with ...

Modelling transport processes in stellar radiative interiors
EPJ 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.

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

Stellar ages from asteroseismology [PDF]
, 2008 Asteroseismology provides powerful means to probe stellar interiors. The oscillations frequencies are closely related to stellar interior properties via the density and sound speed profiles.

Gravitational antiscreening in stellar interiors [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 A new class of relativistic stellar structure equations which include the effects of an energy-dependent Newton coupling is presented. Significant modifications in the mass-radius relation for neutron stars are possible only if the running of the Newton coupling due to quantum gravity occurs at low energies.

Towards a new generation of multi-dimensional stellar evolution models: development of an implicit hydrodynamic code [PDF]
, 2011 This paper describes the first steps of development of a new multidimensional time implicit code devoted to the study of hydrodynamical processes in stellar interiors. The code solves the hydrodynamical equations in spherical geometry and is based on the

White-Dwarf Asteroseismology With the Kepler Space Telescope
Frontiers 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 ...

Structure and Evolution of Low-Mass Stars: An Overview and Some Open Problems [PDF]
, 2007 A review is presented of some of the ingredients, assumptions and techniques that are used in the computation of the structure and evolution of low-mass stars. Emphasis is placed on several ingredients which are still subject to considerable uncertainty.

Turbulence in Stellar Interiors [PDF]
International 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 ...
