Toward a New Paradigm in the Analysis of Asteroseismic Lightcurves
Frontiers 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.

Optical long baseline intensity interferometry: prospects for stellar physics [PDF]
Experimental astronomy (Print), 2018 More than sixty years after the first intensity correlation experiments by Hanbury Brown and Twiss, there is renewed interest for intensity interferometry techniques for high angular resolution studies of celestial sources.

Stellar test of the physics of unification [PDF]
Physical Review D, 2012 We discuss the feasibility of using solar-type main-sequence stars as probes of fundamental physics and unification. We use a simple polytropic stellar structure model and study its sensitivity to variations of the gravitational, strong and electroweak coupling constants in the context of unification scenarios.

Stellar Structure and Evolution
Fundamentals of Astrophysics, 2021 These lecture notes are intended for an advanced astrophysics course on Stellar Structure and Evolution given at Utrecht University (NS-AP434M). Their goal is to provide an overview of the physics of stellar interiors and its application to the theory of

A Review of the Mixing Length Theory of Convection in 1D Stellar Modeling [PDF]
Galaxies, 2023 We review the application of the one-dimensional Mixing Length Theory (MLT) model of convection in stellar interiors and low-mass stellar evolution.

Stellar evolution and the Standard Solar Model [PDF]
EPJ 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

It's written in the massive stars: The role of stellar physics in the formation of black holes [PDF]
Astronomy & AstrophysicsIn the age of gravitational-wave (GW) sources and newly discovered local black holes (BHs) and neutron stars (NSs), understanding the fate of stars is a key question.

From stellar haloes to intracluster light: the physics of the Intra-Halo Stellar Component in cosmological hydrodynamical simulations [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We study the Intra-Halo Stellar Component (IHSC) of Milky Way-mass systems up to galaxy clusters in the Horizon-AGN cosmological hydrodynamical simulation.

Opacity calculation for target physics using the ABAKO/RAPCAL code [PDF]
, 2010 Radiative properties of hot dense plasmas remain a subject of current interest since they play an important role in inertial confinement fusion (ICF) research, as well as in studies on stellar physics.
