Characterization of the HD 17156 planetary system
M. Barbieri, R. Alonso, S. Desidera +11
AIMS : To improve the parameters of the HD 17156 system (peculiar due to the eccentric and long orbital period of its transiting planet) and constrain the presence of stellar compa…
Transiting exoplanets from the CoRoT space mission VI. CoRoT-Exo-3b: The first secure inhabitant of the brown-dwarf desert
M. Deleuil, H. J. Deeg, R. Alonso +2
Context. The CoRoT space mission routinely provides high-precision photometric measurements of thousands of stars that have been continuously observed for months. Aims. The discove…
Limits to the planet candidate GJ 436c
R. Alonso, M. Barbieri, M. Rabus +3
We report on H-band, ground-based observations of a transit of the hot Neptune GJ 436b. Once combined to achieve sampling equivalent to archived observations taken with Spitzer, ou…
Transiting exoplanets from the CoRoT space mission II. CoRoT-Exo-2b: A transiting planet around an active G star
R. Alonso, M. Auvergne, A. Baglin +40
Context. The CoRoT mission, a pioneer in exoplanet searches from space, has completed its first 150 days of continuous observations of ~12000 stars in the galactic plane. An analys…
HD 17156b: A Transiting Planet with a 21.2 Day Period and an Eccentric Orbit
M. Barbieri, R. Alonso, G. Laughlin +8
We report the detection of transits by the 3.1 M_Jup companion to the V=8.17 G0V star HD 17156. The transit was observed by three independant observers on Sept. 9/10, 2007 (two in…
Dispersal of planets hosted in binaries, transitional members of multiple star systems
F. Marzari, M. Barbieri
This paper explains why planets in binary star systems might have a lower frequency. A transient triple state of the binary causes the dispersal of planets.
