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 the exoplanet-host F-type star 94 Ceti : impact of atomic diffusion on the stellar parameters
M. Deal, M. E. Escobar, S. Vauclair +3
A precision of order one percent is needed on the parameters of exoplanet-hosts stars in order to correctly characterize the planets themselves. This will be achieved by asteroseis…
Importance of fingering convection for accreting white dwarfs in the framework of full evolutionary calculations: the case of the hydrogen-rich white dwarfs GD133 and G29-38
F. C. Wachlin, G. Vauclair, S. Vauclair +1
A large fraction of white dwarf stars shows photospheric chemical composition polluted by heavy elements accreted from a debris disk. Such debris disks result from the tidal disrup…
Accretion from debris disks onto white dwarfs : Fingering (thermohaline) instability and derived accretion rates
M. Deal, S. Deheuvels, G. Vauclair +2
Recent observations of a large number of DA and DB white dwarfs show evidence of debris disks, which are the remnants of old planetary systems. The infrared excess detected with \e…
Accurate p-mode measurements of the G0V metal-rich CoRoT target HD 52265
J. Ballot, L. Gizon, R. Samadi +27
The star HD 52265 is a G0V metal-rich exoplanet-host star observed in the seismology field of the CoRoT space telescope from November 2008 to March 2009. The satellite collected 11…
The seismology programme of CoRoT
E. Michel, A. Baglin, M. Auvergne +1
We introduce the main lines and specificities of the CoRoT Seismology Core Programme. The development and consolidation of this programme has been made in the framework of the CoRo…
