Homogeneous comparison of planet candidates imaged directly until 2008

Abstract

We present a compilation of the planet candidates currently known from direct imaging. We have gathered available data from the literature and derive the luminosity of all candidates in a homogeneous way using a bolometric correction, the distances and the K band magnitudes of the objects. In a final step we find the masses of the candidates from a comparison of the luminosity or, if not available, an absolute brightness and several well known hot-start evolutionary models.Comment: 4 pages, 1 figure, Proceedings of the 2nd Subaru International Conference on Exoplanets and Disks: Their Formation and Diversity, Keauhou - Hawaii - USA, 9-12 March 2009; 2nd version: Several typos correcte
