Searching For Giant Exoplanets Around M-dwarf Stars (GEMS) I: Survey Motivation
Recent discoveries of transiting giant exoplanets around M-dwarf stars (GEMS), aided by the all-sky coverage of TESS, are starting to stretch theories of planet formation through the core-accretion scenario. Recent […]

Predicting the Yield of Small Transiting Exoplanets around Mid-M and Ultra-Cool Dwarfs in the Nancy Grace Roman Space Telescope Galactic Bulge Time Domain Survey
We simulate the yield of small (0.5-4.0 R⊕) transiting exoplanets around single mid-M and ultra-cool dwarfs (UCDs) in the Nancy Grace Roman Space Telescope Galactic Bulge Time Domain Survey.

TOI-1695 b: A Keystone Water World Elucidating Radius Valley Emergence Mechanisms Around Early M Dwarfs
Characterizing the bulk compositions of transiting exoplanets within the M dwarf radius valley (i.e. keystone planets) offers a unique means to establish whether the radius valley emerges from an atmospheric […]
