The potential of asteroseismology for probing the core chemical stratification in white dwarf stars
N. Giammichele, S. Charpinet, P. Brassard +2
Context. The details of the C/O core structure in white dwarf stars has mostly remained inaccessible to the technique of asteroseismology, despite several attempts carried out in t…
Toward High Precision Seismic Studies of White Dwarf Stars: Parametrization of the Core and Tests of Accuracy
N. Giammichele, S. Charpinet, G. Fontaine +1
We present a prescription for parametrizing the chemical profile in the core of white dwarfs in the light of the recent discovery that pulsation modes may sometimes be deeply confi…
Signatures of nonlinear mode interactions in the pulsating hot B subdwarf star KIC 10139564
Weikai Zong, Stéphane Charpinet, Gérard Vauclair
We analyse 38-month of contiguous short-cadence data, concentrating on mode multiplets induced by the star rotation and on frequencies forming linear combinations that show intrigu…
