Contribution

It provides a comprehensive, uniformly analyzed dataset of directly imaged planet candidates, facilitating comparative studies and future research.

Findings

Homogeneous luminosity and mass estimates for known candidates

Comparison of candidates using multiple hot-start evolutionary models

A curated database for direct imaging planet candidates

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.
