Descripción
We announce the discovery of the transiting planet CoRoT-13b.
Ground-based follow-up in CFHT and IAC80 confirmed CoRoT's observations.
The mass of the planet was measured with the HARPS spectrograph and the
properties of the host star were obtained analyzing HIRES spectra from
the Keck telescope. It is a hot Jupiter-like planet with an orbital
period of 4.04 days, 1.3 Jupiter masses, 0.9 Jupiter radii, and a
density of 2.34 g cm-3. It orbits a G0V star with T_eff = 5
945 K, M* = 1.09 M&sun;, R_* = 1.01
R&sun;, solar metallicity, a lithium content of + 1.45 dex,
and an estimated age of between 0.12 and 3.15 Gyr. The lithium abundance
of the star is consistent with its effective temperature, activity
level, and age range derived from the stellar analysis. The density of
the planet is extreme for its mass, implies that heavy elements are
present with a mass of between about 140 and 300 {M}⊕.
The CoRoT space mission, launched on December 27th 2006, has been
developed and is operated by CNES, with the contribution of Austria,
Belgium, Brazil, ESA (RSSD and Science Programme), Germany and Spain.
Part of the observations were obtained at the Canada-France-Hawaii
Telescope (CFHT) which is operated by the National Research Council of
Canada, the Institut National des Sciences de l'Univers of the Centre
National de la Recherche Scientifique of France, and the University of
Hawaii. Based on observations made with HARPS spectrograph on the 3.6-m
European Organisation for Astronomical Research in the Southern
Hemisphere telescope at La Silla Observatory, Chile (ESO program
184.C-0639). Based on observations made with the IAC80 telescope
operated on the island of Tenerife by the Instituto de
Astrofísica de Canarias in the Spanish Observatorio del Teide.
Part of the data presented herein were obtained at the W. M. Keck
Observatory, which is operated as a scientific partnership among the
California Institute of Technology, the University of California and the
National Aeronautics and Space Administration. The Observatory was made
possible by the generous financial support of the W. M. Keck Foundation.
