The ELODIE survey for northern extra-solar planets IV. HD196885, a close binary star with a 3.7-year planet
A. C. M. Correia, S. Udry, M. Mayor +9
Aims:We aim to significantly increase the number of detected extra-solar planets in a magnitude-limited sample to improve our knowledge of their orbital element distributions and t…
The CORALIE survey for southern extra-solar planets XV. Discovery of two eccentric planets orbiting HD4113 and HD156846
O. Tamuz, D. Ségransan, S. Udry +10
We report the detection of two very eccentric planets orbiting HD4113 and HD156846 with the CORALIE Echelle spectrograph mounted on the 1.2-m Euler Swiss telescope at La Silla. The…
Probing the Impact of Stellar Duplicity on Planet Occurrence with Spectroscopic and Imaging Observations
A. Eggenberger, S. Udry
Although it is commonly agreed that the presence of a close stellar companion is likely to affect planet formation and evolution, the precise effects and their actual impact on pla…
No evidence of a hot Jupiter around HD 188753 A
A. Eggenberger, S. Udry, T. Mazeh +2
The discovery of a short-period giant planet (a hot Jupiter) around the primary component of the triple star system HD 188753 has often been considered as an important observationa…
