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.

Introducing EMP-Pathfinder: modelling the simultaneous formation and evolution of stellar clusters in their host galaxies [PDF]
Monthly notices of the Royal Astronomical Society, 2022 The formation and evolution of stellar clusters is intimately linked to that of their host galaxies. To study this connection, we present the emp-Pathfindersuite of cosmological zoom-in Milky Way-mass simulations.

The stellar atmosphere physical system I. Phenomenological definition and representation of a stellar atmosphere [PDF]
Serbian Astronomical Journal, 2018 This paper is the first in a series of two that deals with the physical and numerical grounds of stellar atmosphere modelling. After a phenomenological definition of a star and stellar atmosphere, the physics that shapes the stellar atmosphere ...

The Astronomical Journal, 2023 In this paper, we report on the follow-up of six potential exoplanets detected with Gaia astrometry and provide an overview of what is currently known about the nature of the entire Gaia astrometric exoplanet candidate sample, 72 systems in total.

Radiative stellar feedback in galaxy formation: Methods and physics [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Radiative feedback (RFB) from stars plays a key role in galaxies, but remains poorly understood. We explore this using high-resolution, multifrequency radiation-hydrodynamics (RHD) simulations from the Feedback In Realistic Environments (FIRE) project.

Production rates of dark photons and Z' in the Sun and stellar cooling bounds
Journal of Cosmology and Astroparticle Physics, 2023 Light weakly interacting particles could be copiously produced in the Sun which, as a well-understood star, could provide severe constraints on such new physics. In this work, we calculate the solar production rates of light gauge bosons (e.g.

Turbulence-supported Massive Star Envelopes
The Astrophysical Journal Letters, 2023 The outer envelopes of massive ( M ≳ 10 M _⊙ ) stars exhibit large increases in opacities from forests of lines and ionization transitions (particularly from iron and helium) that trigger near-surface convection zones. One-dimensional (1D) models predict
