The cradle of nonlinear asteroseismology: observations of oscillation mode variability in compact pulsating stars
Weikai Zong, Stéphane Charpinet, Gérard Vauclair +2
We briefly review progress in developing a pathway to nonlinear astereoseismology, both from theoretical and observational aspects. As predicted by the theory of weak nonlinear int…
New simulations of accreting DA white dwarfs: inferring accretion rates from the surface contamination
F. C. Wachlin, G. Vauclair, S. Vauclair +1
A non negligible fraction of white dwarf stars show the presence of heavy elements in their atmospheres. The most accepted explanation for this contamination is the accretion of ma…
Oscillation mode variability in evolved compact pulsators from Kepler photometry. II. Comparison of modulationpatterns between raw and corrected flux
Weikai Zong, Stephane Charpinet, Gerard Vauclair
We present the second results of an ensemble and systematic survey of oscillation mode variability in compact pulsators observed with the original {\sl Kepler} mission. Two types o…
Precise determination of stellar parameters of the ZZ Ceti and DAZ white dwarf GD 133 through asteroseismology
J. -N. Fu, G. Vauclair, J. Su +15
An increasing number of white dwarf stars show atmospheric chemical composition polluted by heavy elements accreted from debris disk material. The existence of such debris disks st…
He white dwarfs with large H contamination: Convective mixing or accretion?
F. C. Wachlin, G. Vauclair, S. Vauclair
White dwarfs are compact objects with atmospheres containing mainly light elements, hydrogen or helium. Because of their surface high gravitational field, heavy elements diffuse do…
Asteroseismology of the ZZ Ceti star KUV 08368+4026
C. Li, J. -N. Fu, G. Vauclair +5
Asteroseismology is a unique tool to explore the internal structure of stars through both observational and theoretical research. The internal structure of pulsating hydrogen shell…
