Ground-based parallax confirmed by Spitzer: binary microlensing event MOA-2015-BLG-020
Tianshu Wang, Wei Zhu, Shude Mao +83
We present the analysis of the binary gravitational microlensing event MOA-2015-BLG-020. The event has a fairly long timescale (about 63 days) and thus the light curve deviates sig…
OGLE-2014-BLG-0289: Precise Characterization of a Quintuple-Peak Gravitational Microlensing Event
A. Udalski, C. Han, V. Bozza +63
We present the analysis of the binary-microlensing event OGLE-2014-BLG-0289. The event light curve exhibits very unusual five peaks where four peaks were produced by caustic crossi…
OGLE-2012-BLG-0950Lb: The First Planet Mass Measurement from Only Microlens Parallax and Lens Flux
N. Koshimoto, A. Udalski, J. P. Beaulieu +38
We report the discovery of a microlensing planet OGLE-2012-BLG-0950Lb with the planet/host mass ratio of . A long term distortion detected in both MOA and…
OGLE-2013-BLG-1761Lb: A Massive Planet Around an M/K Dwarf
Y. Hirao, A. Udalski, T. Sumi +37
We report the discovery and the analysis of the planetary microlensing event, OGLE-2013-BLG-1761. There are some degenerate solutions in this event because the planetary anomaly is…
Spitzer Parallax of OGLE-2015-BLG-0966: A Cold Neptune in the Galactic Disk
R. A. Street, A. Udalski, S. Calchi Novati +106
We report the detection of a Cold Neptune m_planet=21+/-2MEarth orbiting a 0.38MSol M dwarf lying 2.5-3.3 kpc toward the Galactic center as part of a campaign combining ground-base…
Spitzer Microlensing Parallax for OGLE-2016-BLG-1067: a sub-Jupiter Orbiting an M-dwarf in the Disk
S. Calchi Novati, D. Suzuki, A. Udalski +65
We report the discovery of a sub-Jupiter mass planet orbiting beyond the snow line of an M-dwarf most likely in the Galactic disk as part of the joint Spitzer and ground-based moni…
