Seismic signature of a magnetic field in the Doradus star KIC 2309579
S. Ihallaine, J. Ballot, F. Lignières +4
Internal magnetic fields have recently been detected and measured in the radiative core of red giant stars using asteroseismology. Being one of red giant stars progenitors and exhi…
Dilution of accreted planetary matter in hot DA white dwarfs according to their mass
M. Deal, S. Vauclair, S. Charpinet +1
A large proportion of observed white dwarfs (WDs) show evidence of debris disks, remnants of the former planetary systems, and/or signatures of heavy elements in their atmospheres,…
Asteroseismology of white dwarfs in the 2040s
Murat Uzundag, Ingrid Pelisoli, Stephane Charpinet +6
White dwarfs, the final evolutionary stage of the vast majority of stars, serve as critical tools for cosmochronology, studies of planetary system evolution, and laboratories for n…
The Arizona-Montréal spectroscopic survey of hot subluminous stars
M. Latour, E. M. Green, M. Dorsch +6
Hot subdwarf B (sdB) and O (sdO) type stars are evolved helium-burning objects that lost their hydrogen envelope before the helium flash when their progenitors were close to the ti…
