A uniformly derived catalogue of exoplanets from radial velocities

Abstract

A new catalogue of extrasolar planets is presented by re-analysing a selection of published radial velocity data sets using exofit. All objects are treated on an equal footing within a Bayesian framework to give orbital parameters for 94 exoplanetary systems. Model selection (between one- and two-planet solutions) is then performed using both a visual flagging method and a standard chi-square analysis, with agreement between the two methods for 99per cent of the systems considered. The catalogue is to be made available online, and this 'proof of concept' study may be maintained and extended in the future to incorporate all systems with publicly available radial velocity data, as well as transit and microlensing data. © 2012 The Authors Monthly Notices of the Royal Astronomical Society © 2012 RAS.
