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…
Differential asteroseismic study of seismic twins observed by CoRoT; Comparison of HD 175272 with HD 181420
N. Ozel, B. Mosser, M. A. Dupret +12
The CoRoT short asteroseismic runs give us the opportunity to observe a large variety of late-type stars through their solar-like oscillations. We report the observation and modeli…
Kepler White Paper: Asteroseismology of Solar-Like Oscillators in a 2-Wheel Mission
W. J Chaplin, H. Kjeldsen, J. Christensen-Dalsgaard +53
We comment on the potential for continuing asteroseismology of solar-type and red-giant stars in a 2-wheel Kepler Mission. Our main conclusion is that by targeting stars in the ecl…
Seismic constraints on rotation of Sun-like star and mass of exoplanet
Laurent Gizon, Jérome Ballot, Eric Michel +32
Rotation is thought to drive cyclic magnetic activity in the Sun and Sun-like stars. Stellar dynamos, however, are poorly understood owing to the scarcity of observations of rotati…
Stellar ages and convective cores in field main-sequence stars: first asteroseismic application to two Kepler targets
V. Silva Aguirre, S. Basu, I. M. Brandão +21
Using asteroseismic data and stellar evolution models we make the first detection of a convective core in a Kepler field main-sequence star, putting a stringent constraint on the t…
Properties of oscillation modes in subgiant stars observed by Kepler
O. Benomar, T. R. Bedding, B. Mosser +7
Mixed modes seen in evolved stars carry information on their deeper layers that can place stringent constraints on their physics and on their global properties (mass, age, etc...).…
