CoRoT measures solar-like oscillations and granulation in stars hotter than the Sun
E. Michel, A. Baglin, M. Auvergne +2
Oscillations of the Sun have been used to understand its interior structure. The extension of similar studies to more distant stars has raised many difficulties despite the strong…
The exoplanet-host star iota Horologii: an evaporated member of the primordial Hyades cluster
S. Vauclair, M. Laymand, F. Bouchy +4
We show that the exoplanet-host star iota Horologii, alias HD17051, which belongs to the so-called Hyades stream, was formed within the primordial Hyades stellar cluster and has ev…
Whole Earth Telescope observations of the hot helium atmosphere pulsating white dwarf EC 20058-5234
WET Collaboration, D. J. Sullivan, T. S. Metcalfe +22
We present the analysis of a total of 177h of high-quality optical time-series photometry of the helium atmosphere pulsating white dwarf (DBV) EC 20058-5234. The bulk of the observ…
The pulsation modes of the pre-white dwarf PG 1159-035
J. E. S. Costa, S. O. Kepler, D. E. Winget +74
PG 1159-035, a pre-white dwarf with T_eff=140,000 K, is the prototype of both two classes: the PG1159 spectroscopic class and the DOV pulsating class. Previous studies of PG 1159-0…
Asteroseismological constraints on the coolest GW Vir variable star (PG 1159-type)PG 0122+200
A. H. Córsico, M. M. Miller Bertolami, L. G. Althaus +2
We present an asteroseismological study on PG 0122+200, the coolest known pulsating PG1159 (GW Vir) star. Our results are based on an augmented set of the full PG1159 evolutionary…
Abell 43: Longest period Planetary Nebula Nucleus variable
J. -E. Solheim, G. Vauclair, A. S. Mukadam +2
Based on 24h high speed photometry of the hybrid PG 1159 star Abell 43, we have detected 6 sighificant pulsations with periods between 2380 s and 6075 s. A short (4h) run on the al…
