The HARPS search for southern extra-solar planets. IX. Exoplanets orbiting HD 100777, HD 190647, and HD 221287
Dominique Naef, Michel Mayor, Willy Benz +8
The HARPS high-resolution high-accuracy spectrograph is offered to the astronomical community since the second half of 2003. Since then, we have been using this instrument for moni…
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…
The transiting planet OGLE-TR-132b revisited with new spectroscopy and deconvolution photometry
M. Gillon, F. Pont, C. Moutou +8
OGLE-TR-132b transits a very metal-rich F dwarf about 2000 pc from the Sun, in the Galactic disc towards Carina. It orbits very close to its host star (a = 0.03 AU) and has an equi…
The `666' collaboration on OGLE transits: I. Accurate radius of the planets OGLE-TR-10b and OGLE-TR-56b with VLT deconvolution photometry
Frederic Pont, Claire Moutou, Michael Gillon +14
Transiting planets are essential to study the structure and evolution of extra-solar planets. For that purpose, it is important to measure precisely the radius of these planets. He…
On the Age of Stars Harboring Transiting Planets
C. Melo, N. C. Santos, F. Pont +5
Results of photometric surveys have brought to light the existence of a population of giant planets orbiting their host stars even closer than the hot Jupiters (HJ), with orbital p…
