A calibration of the Rossby number from asteroseismology [PDF]

open access: yesAstronomy & Astrophysics, 2021
Stellar activity and rotation are tightly related in a dynamo process. Our understanding of this mechanism is mainly limited by our capability of inferring the properties of stellar turbulent convection.

Radial Oscillations in Neutron Stars from Unified Hadronic and Quarkyonic Equation of States

open access: yesGalaxies, 2023
We study radial oscillations in non-rotating neutron stars by considering the unified equation of states (EoSs), which support the 2 M⊙ star criterion.

TESS Data for Asteroseismology (T’DA) Stellar Variability Classification Pipeline: Setup and Application to the Kepler Q9 Data [PDF]

open access: yesAstronomical Journal, 2021
The NASA Transiting Exoplanet Survey Satellite (TESS) is observing tens of millions of stars with time spans ranging from ∼27 days to about 1 yr of continuous observations.

Gravitational wave asteroseismology of dark matter hadronic stars [PDF]

open access: yesPhysical Review D
The influence of the dark matter mass~($M_{\chi}$) and the Fermi momentum~($k_{F}^{\dm}$) on the $f_0$-mode oscillation frequency, damping time parameter, and tidal deformability of hadronic stars are studied by employing a numerical integration of ...

TESS Data for Asteroseismology: Light-curve Systematics Correction [PDF]

open access: yesAstrophysical Journal Supplement Series, 2021
Data from the Transiting Exoplanet Survey Satellite (TESS) have produced of the order of one million light curves at cadences of 120 s and especially 1800 s for every ∼27 day observing sector during its two-year nominal mission.

Asteroseismology of Procyon with SOPHIE [PDF]

open access: yesAstronomy & Astrophysics, 2007
This paper reports a 9-night asteroseismic observation program conducted in January 2007 with the new spectrometer Sophie at the OHP 193-cm telescope, on the F5 IV-V target Procyon A. This first asteroseismic program with Sophie was intended to test the performance of the instrument with a bright but demanding asteroseismic target and was part of a ...

Pulsating stars harbouring planets

open access: yesEPJ Web of Conferences, 2013
Why bother with asteroseismology while studying exoplanets? There are several answers to this question. Asteroseismology and exoplanetary sciences have much in common and the synergy between the two opens up new aspects in both fields.

Asteroseismology [PDF]

open access: yesPhysics Today, 2015
Pulsations known as starquakes can provide precious glimpses into a star’s interior—and clues to how the star will live and die.

Constraining stellar evolution theory with asteroseismology of γ Doradus stars using deep learning [PDF]

open access: yesAstronomy & Astrophysics, 2021
Context. The efficiency of the transport of angular momentum and chemical elements inside intermediate-mass stars lacks proper calibration, thereby introducing uncertainties on a star’s evolutionary pathway.
