SOAP-T: A tool to study the light-curve and radial velocity of a system with a transiting planet and a rotating spotted star
M. Oshagh, I. Boisse, G. Boué +4
We present an improved version of SOAP (Boisse et al. 2012) named "SOAP-T", which can generate the radial velocity variations and light-curves for systems consisting of a rotating…
A new analysis of the WASP-3 system: no evidence for an additional companion
M. Montalto, J. Gregorio, G. Boue' +7
In this work we investigate the problem concerning the presence of additional bodies gravitationally bounded with the WASP-3 system. We present eight new transits of this planet an…
Comparing HARPS and Kepler surveys: The alignment of multiple-planet systems
P. Figueira, M. Marmier, G. Boué +6
Aims. We study a subset of the planetary population characterized both by HARPS and Kepler surveys. We compare the statistical properties of planets in systems with m.sin i >5-10 M…
Degeneracy in the characterization of non-transiting planets from transit timing variations
Gwenaël Boué, Mahmoudreza Oshagh, Marco Montalto +1
The transit timing variation (TTV) method allows the detection of non-transiting planets through their gravitational perturbations. Since TTVs are strongly enhanced in systems clos…
Metallicities for 6 nearby open clusters from high-resolution spectra of giant stars. [Fe/H] values for a planet search sample
N. C. Santos, C. Lovis, J. Melendez +3
We present a study of the stellar parameters and iron abundances of 18 giant stars in 6 open clusters. The analysis was based on high-resolution and high-S/N spectra obtained with…
