The PRime-focus Infrared Microlensing Experiment (PRIME): First Results

The Astronomical Journal
We present the description of the instruments and the first results of the PRime-focus Infrared Microlensing Experiment (PRIME). PRIME is the first dedicated near-infrared (NIR) microlensing survey telescope, and is located at the South African ...

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 ...

Microlensing Results Challenge the Core Accretion Runaway Growth Scenario for Gas Giants

, 2018
We compare the planet-to-star mass-ratio distribution measured by gravitational microlensing to core accretion theory predictions from population synthesis models.

Predictions of the Nancy Grace Roman Space Telescope Galactic Exoplanet Survey. III. Detectability of Giant Exomoons of Wide-separation Giant Planets

The Astronomical Journal
The Nancy Grace Roman Space Telescope (Roman) will conduct a Galactic Exoplanet Survey to discover bound and free-floating exoplanets using gravitational microlensing. Roman should be sensitive to lenses with mass down to ∼0.02 M _⊕ , or roughly the mass

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 ...

Simulating Gravitational Microlensing Events by TESS: Predictions on Statistics and Properties

The Astronomical Journal
We study the statistics and properties of microlensing events that can be detected by the Transiting Exoplanet Survey Satellite (TESS) based on Monte Carlo simulations. We simulate potential microlensing events from a sample of TESS Candidate Target List
