KMT-2024-BLG-3237: Another Free-floating Planet Candidate with Angular Einstein Radius Measurement

The Astronomical Journal
Planet-formation theories suggest the presence of free-floating planets (FFPs) that are ejected from their formation sites. While these planets emit very little light, they can be identified through gravitational microlensing.

Mass Production of 2023 KMTNet Microlensing Planets. I. Low Mass Ratio

The Astronomical Journal
We initiate the systematic search for planets in the 2023 data of the Korea Microlensing Telescope Network (KMTNet), focusing on those planets found by the KMTNet AnomalyFinder with low preliminary estimates of the mass ratio, q

Simulations of Gravitational Microlensing

, 2011
Gravitational microlensing occurs when a massive lens (typically a star) deflects lightfrom a more distant source, creating two unresolvable images that are magnified. Theeffect is transient due to the motions of the lens and source, and the changing magnificationgives rise to a characteristic lightcurve.
