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.

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.

White Dwarfs as Physics Laboratories: Lights and Shadows

open access: yesFrontiers in Astronomy and Space Sciences, 2022
The evolution of white dwarfs is essentially a gravothermal process of cooling in which the basic ingredients for predicting their evolution are well identified, although not always well understood. There are two independent ways to test the cooling rate.

Saturn's Rings as a Seismograph to Probe Saturn's Internal Structure

open access: yesAGU Advances, Volume 1, Issue 2, June 2020., 2020
As it has already done for Earth, the Sun, and the stars, seismology has the potential to radically change the way the interiors of giant planets are studied. In a sequence of events foreseen by only a few, observations of Saturn's rings by the Cassini spacecraft have rapidly broken ground on giant planet seismology. Gravity directly couples the planet'

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 ...

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.

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 ...

Asteroseismology of solar-type stars [PDF]

open access: yesLiving Reviews in Solar Physics, 2019
Until the last few decades, investigations of stellar interiors had been restricted to theoretical studies only constrained by observations of their global properties and external characteristics.

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.
