Angular Momentum Transport in Stellar Interiors [PDF]
, 2018 Stars lose a significant amount of angular momentum between birth and death, implying that efficient processes transporting it from the core to the surface are active.

Asteroseismology of Close Binary Stars: Tides and Mass Transfer
Frontiers 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

Stars in the age of micro-arc-second astrometry [PDF]
, 2007 The understanding and modeling of the structure and evolution of stars is based on statistical physics as well as on hydrodynamics. Today, a precise identification and proper description of the physical processes at work in stellar interiors are still ...

Solar-Like Oscillators in the Kepler Era: A Review
Frontiers 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 ...

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.

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.

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.

Baroclinically-driven flows and dynamo action in rotating spherical fluid shells [PDF]
, 2017 The dynamics of stably stratified stellar radiative zones is of considerable interest due to the availability of increasingly detailed observations of Solar and stellar interiors.
