Asteroseismology of solar-type stars: signatures of convective and/or helium cores
M. Soriano, S. Vauclair
Asteroseismology of solar-type stars is an important tool for constraining stellar parameters and internal structure. Several frequency combinations are largely used for comparison…
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…
CS22964-161: A Double-Lined Carbon- and s-Process-Enhanced Metal-Poor Binary Star
Ian B. Thompson, Inese I. Ivans, Sara Bisterzo +6
A detailed high-resolution spectroscopic analysis is presented for the carbon-rich low metallicity Galactic halo object CS 22964-161. We have discovered that CS 22964-161 is a doub…
Asteroseismology of alpha Cen A. Evidence of rotational splitting
M. Bazot, F. Bouchy, H. Kjeldsen +3
Asteroseismology provides a unique tool for studying stellar interiors. Recently p modes have been detected on the bright solar-like star alpha Cen A thanks to high-precision radia…
Asteroseismology of the planet-hosting star Arae. I. The acoustic spectrum
Francois Bouchy, Michael Bazot, N. C. Santos +2
We present HARPS spectroscopy of mu Arae (HD160691) performed for studying the origin of the metallicity excess in this planet-hosting stars. The asteroseismologic campaign led to…
The HARPS survey for southern extra-solar planets II. A 14 Earth-masses exoplanet around mu Arae
N. C. Santos, F. Bouchy, M. Mayor +13
In this letter we present the discovery of a very light planetary companion to the star mu Ara (HD160691). The planet orbits its host once every 9.5days, and induces a sinusoidal r…
