Techniques for Constraining the Abundance of Nonplanetary Substellar Objects

Abstract : An interesting problem of relativistic astrophysics is the possible existence of non planetary Compact SubStellar Objects (CSSOs), such as black holes, but also non-standard objects such as boson stars. The challenge is to detect and distinguish them from ordinary planets. Here we present a new approach to this problem, which consists in detecting directly these CSSOs using exoplanet searches by transits, radial velocity measurements and astrometry and comparing the results to standard planet models.
