Planet Mass Function around M Stars at 1–10 au: A Plethora of Sub-Earth Mass Objects

The Astrophysical Journal
Small planets (≲1 M _⊕ ) at intermediate orbital distances (∼1 au) represent an uncharted territory in exoplanetary science. The upcoming microlensing survey by the Nancy Grace Roman Space Telescope will be sensitive to objects as light as Ganymede and ...

Towards A Census of Earth-mass Exo-planets with Gravitational Microlensing

, 2008
Thirteen exo-planets have been discovered using the gravitational microlensing technique (out of which 7 have been published). These planets already demonstrate that super-Earths (with mass up to ~10 Earth masses) beyond the snow line are common and ...

The Robo-AO-2 facility for rapid visible/near-infrared AO imaging and the demonstration of hybrid techniques [PDF]

, 2018
We are building a next-generation laser adaptive optics system, Robo-AO-2, for the UH 2.2-m telescope that will deliver robotic, diffraction-limited observations at visible and near-infrared wavelengths in unprecedented numbers.

OGLE-2016-BLG-1195Lb: A Sub-Neptune Beyond the Snow Line of an M-dwarf Confirmed by Keck Adaptive Optics

The Astronomical Journal
We present the analysis of high-resolution follow-up observations of OGLE-2016-BLG-1195 using Laser Guide Star Adaptive Optics with Keck, seven years after the event’s peak.

The Brown-dwarf Desert Persists as a Mass-ratio Desert around Low-mass Stars

The Astrophysical Journal Letters
Sun-like stars are known to host a paucity of brown-dwarf companions at close separations. Direct imaging surveys of intermediate-mass stars have suggested that the brown-dwarf desert may be fundamentally a feature in the mass ratio. Microlensing surveys

The Roman Microlensing Survey: Confirmation or Refutation of Gas Giant Exoplanet Formation Theories

Astrophysical Journal
Exoplanet research has moved from the discovery of new classes of planets toward creating a census of exoplanet population demographics across the spectrum of exoplanet and host star masses.
