Techniques for Constraining the Abundance of Nonplanetary Substellar Objects
Résumé
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.
