Abstract

A new extra-solar planet has been discovered in the context of the CORALIE survey at La Silla Observatory. This new planetary candidate orbits the star HD 192263 in an almost circular orbit at a distance of 0.15 AU, producing a 24.13 day periodic radial-velocity variation, with a semi-amplitude of 62 m s-1. The derived minimum mass of the planet is 0.73 M[FORMULA].

Key words: techniques: radial velocities – solar system: general – stars: individual: HD 192263 – planetary systems

* Based on observations collected at the La Silla Observatory, ESO (Chile), with the echelle spectrograph CORALIE at the 1.2-m Euler Swiss telescope
