Title: Exosatellite Detected Around a Companion Brown Dwarf

Speaker: Kevin Hoy (Universidad Diego Portales/ESO)

Abstract:

The search for exomoons has yielded a few candidates, yet none has ever been confirmed. In this work, we apply the radial velocity method to search for satellites around directly-imaged brown dwarf companions and giant exoplanets. We have found strong evidence for at least one Jupiter-mass satellite orbiting the companion brown dwarf CD-35 2722 B. This system blurs the lines between what we might commonly consider planets and moons, serving as a useful early analogue for the first unambiguous exomoon detection we expect in the not-too-distant future.
