Reanalyses of Anomalous Gravitational Microlensing Events in the OGLE-III Early Warning System Database with Combined Data

J. Jeong, H. Park, C. Han +95

We reanalyze microlensing events in the published list of anomalous events that were observed from the OGLE lensing survey conducted during 2004-2008 period. In order to check the…

Pathway to the Galactic Distribution of Planets: Combined Spitzer and Ground-Based Microlens Parallax Measurements of 21 Single-Lens Events

S. Calchi Novati, A. Gould, A. Udalski +82

We present microlens parallax measurements for 21 (apparently) isolated lenses observed toward the Galactic bulge that were imaged simultaneously from Earth and Spitzer, which was…

OGLE-2011-BLG-0265Lb: a Jovian Microlensing Planet Orbiting an M Dwarf

J. Skowron, I. -G. Shin, A. Udalski +121

We report the discovery of a Jupiter-mass planet orbiting an M-dwarf star that gave rise to the microlensing event OGLE-2011-BLG-0265. Such a system is very rare among known planet…

A Terrestrial Planet in a ~1 AU Orbit Around One Member of a ~15 AU Binary

A. Gould, A. Udalski, I. -G. Shin +61

We detect a cold, terrestrial planet in a binary-star system using gravitational microlensing. The planet has low mass (2 Earth masses) and lies projected at ~ 0.8 a…

OGLE-2012-BLG-0455/MOA-2012-BLG-206: Microlensing event with ambiguity in planetary interpretations caused by incomplete coverage of planetary signal

H. Park, C. Han, A. Gould +55

Characterizing a microlensing planet is done from modeling an observed lensing light curve. In this process, it is often confronted that solutions of different lensing parameters r…

MOA-2013-BLG-220Lb: Massive Planetary Companion to Galactic-Disk Host

J. C. Yee, C. Han, A. Gould +70

We report the discovery of MOA-2013-BLG-220Lb, which has a super-Jupiter mass ratio relative to its host. The proper motion, $μ=12.5\pm 1\, {\rm mas}…
