Exomoons & Demographics

Exomoon & Exosatellite detection methods: 

We are search for transiting exosatellites and exomoons in the lightucurves of directly monitored wide-orbit exoplanets, free-floating planets and brown dwarfs

Transiting Exosatellites, Moons, and Planets in Orion (TEMPO) Survey: 


This is a proposed 30-day survey with the Roman Space Telescope led by Melinda Soares-Furtado, Andrew Vanderburg and myself designed to detect a population of transiting extrasolar satellites, moons, and planets in the Orion Nebula Cluster (ONC). The young (1–3 Myr), densely-populated ONC harbors about a thousand bright brown dwarfs (BDs) and free-floating planetary-mass objects (FFPs)



Demographics:

We are focused on constraining the demographics of companions at host masses and ages that are currently poorly understood. For example, see the archival Spitzer light curve paper above, which constrains the occurrence rates in question illustrated on the right figure. 

We're also working to understand trends within the existing exoplanet population and explore connections to our own solar system.
