HST pre-imaging of a free-floating planet candidate microlensing event

Mateusz Kapusta, Przemek Mroz, Yoon-Hyun Ryu +33

High-cadence microlensing observations uncovered a population of very short-timescale microlensing events, which are believed to be caused by the population of free-floating planet…

Microlensing events indicate that super-Earth exoplanets are common in Jupiter-like orbits

Weicheng Zang, Youn Kil Jung, Jennifer C. Yee +65

Exoplanets classified as super-Earths are commonly observed on short period orbits, close to their host stars, but their abundance on wider orbits is poorly constrained. Gravitatio…

KMT-2023-BLG-1431Lb: A New Microlensing Planet from a Subtle Signature

Aislyn Bell, Jiyuan Zhang, Youn Kil Jung +70

The current studies of microlensing planets are limited by small number statistics. Follow-up observations of high-magnification microlensing events can efficiently form a statisti…
