We report on initial results from the first phase of Exercise 1 of the asteroFLAG hare and hounds. The asteroFLAG group is helping to prepare for the asteroseismology component of…
A new code for automatic determination of equivalent widths: Automatic Routine for line Equivalent widths in stellar Spectra (ARES)
S. G. Sousa, N. C. Santos, G. Israelian +2
We present a new automatic code (ARES) for determining equivalent widths of the absorption lines present in stellar spectra. We also describe its use for determining fundamental sp…
A new Neptune-mass planet orbiting HD 219828
C. Melo, N. C. Santos, W. Gieren +10
Two years ago a new benchmark for the planetary survey was set with the discoveries of three extrasolar planets with masses below 20. In particular, the serendipitous dis…
Spectroscopic metallicities for planet-host stars: extending the samples
N. C. Santos, G. Israelian, M. Mayor +4
We present stellar parameters and metallicities for 29 planet-host stars, as well as for a large volume-limited sample of 53 stars not known to be orbited by any planetary-mass com…
