Asteroseismology of the Hyades red giant and planet host epsilon Tauri [PDF]

open access: yes, 2019
Asteroseismic analysis of solar-like stars allows us to determine physical parameters such as stellar mass, with a higher precision compared to most other methods.

Asteroseismology with SuperWASP [PDF]

open access: yesProceedings of the International Astronomical Union, 2013
AbstractThe highly successful SuperWASP planetary transit finding programme has surveyed a large fraction of both the northern and southern skies. There now exists in its archive over 420 billion photometric measurements for more than 31 million stars.

The CubeSpec space mission

open access: yesAstronomy & Astrophysics
Context. Massive stars play a central role in astrophysics, yet their internal structure remains poorly constrained due to uncertainties regarding their core masses, internal rotation, and chemical mixing.

Modelling Neutron-Star Ocean Dynamics

open access: yesUniverse, 2023
We revisit the calculation of mode oscillations in the ocean of a rotating neutron star, which may be excited during thermonuclear X-ray bursts. Our present theoretical understanding of ocean modes relies heavily on the traditional approximation commonly

The impact of CoRoT on close binary research [PDF]

open access: yes, 2005
The space experiment CoRoT will provide continuous monitoring and high accuracy light curves of about sixty thousand stars. Selected binary systems will be observed in the Additional Program frame as targets of long and continuous pointed observations ...

Asteroseismology of the GW Virginis stars SDSS J0349-0059 and VV 47 [PDF]

open access: yes, 2016
We present an asteroseismological study of SDSS J0349-0059 and VV 47 aimed mainly at deriving their total mass on the basis of state-of-the-art PG 1159 evolutionary models.

Helioseismology in a bottle: modal acoustic velocimetry

open access: yesNew Journal of Physics, 2014
Measurement of the differential rotation of the Sunʼs interior is one of the great achievements of helioseismology, providing important constraints for stellar physics. The technique relies on observing and analyzing rotationally-induced splittings of p -

Nonanalytic Relativistic r-Modes of Slowly Rotating Nonbarotropic Neutron Stars

open access: yesUniverse, 2022
We show that the r-modes of slowly rotating nonbarotropic neutron stars are described by nonanalytic functions of stellar angular velocity, which makes the perturbation techniques, used so far in the r-mode theoretical studies, inapplicable.

Precision Stellar Astrophysics in the Kepler Era

open access: yes, 2016
The study of fundamental properties (such as temperatures, radii, masses, and ages) and interior processes (such as convection and angular momentum transport) of stars has implications on various topics in astrophysics, ranging from the evolution of ...

White-Dwarf Asteroseismology With the Kepler Space Telescope

open access: yesFrontiers in Astronomy and Space Sciences, 2020
In the course of their evolution, white-dwarf stars go through at least one phase of variability in which the global pulsations they undergo allow astronomers to peer into their interiors, making it possible to shed light on their deep inner structure ...
