A terrestrial-mass rogue planet candidate detected in the shortest-timescale microlensing event
P. Mroz, R. Poleski, A. Gould +27
Some low-mass planets are expected to be ejected from their parent planetary systems during early stages of planetary system formation. According to planet-formation theories, such…
OGLE-GAL-ACEP-091 -- The First Known Multi-Mode Anomalous Cepheid
I. Soszyński, R. Smolec, A. Udalski +12
Anomalous Cepheids (ACs) are metal-deficient, core-helium-burning pulsating stars with masses in the range 1.2-2.2 M_S. Until recently, all known ACs were pure single-mode pulsator…
OGLE-2018-BLG-1269Lb: A Jovian Planet With A Bright, Host
Youn Kil Jung, Andrew Gould, Andrzej Udalski +54
We report the discovery of a planet in the microlensing event OGLE-2018-BLG-1269, with planet-host mass ratio , i.e., times smaller than the Jupiter/Su…
A Gas Giant Planet in the OGLE-2006-BLG-284L Stellar Binary System
David P. Bennett, Andrzej Udalski, Ian A. Bond +32
We present the analysis of microlensing event OGLE-2006-BLG-284, which has a lens system that consists of two stars and a gas giant planet with a mass ratio of $q_p = (1.26\pm 0.19…
Microlensing optical depth and event rate in the OGLE-IV Galactic plane fields
Przemek Mroz, Andrzej Udalski, Michal K. Szymanski +10
Searches for gravitational microlensing events are traditionally concentrated on the central regions of the Galactic bulge but many microlensing events are expected to occur in the…
KMT-2019-BLG-1339L: an M Dwarf with a Giant Planet or a Companion Near the Planet/Brown Dwarf Boundary
Cheongho Han, Doeon Kim, Andrzej Udalski +31
We analyze KMT-2019-BLG-1339, a microlensing event with an obvious but incompletely resolved brief anomaly feature around the peak of the light curve. Although the origin of the an…
A free-floating or wide-orbit planet in the microlensing event OGLE-2019-BLG-0551
P. Mroz, R. Poleski, C. Han +30
High-cadence observations of the Galactic bulge by the microlensing surveys led to the discovery of a handful of extremely short-timescale microlensing events that can be attribute…
