OGLE-2017-BLG-0173Lb: Low Mass-Ratio Planet in a "Hollywood" Microlensing Event
K. -H. Hwang, A. Udalski, Y. Shvartzvald +34
We present microlensing planet OGLE-2017-BLG-0173Lb, with planet-host mass ratio either or , the lowest or among the lowest e…
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-2016-BLG-0693LB: Probing the Brown Dwarf Desert with Microlensing
Y. -H. Ryu, A. Udalski, J. C. Yee +25
We present an analysis of microlensing event OGLE-2016-BLG-0693, based on the survey-only microlensing observations by the OGLE and KMTNet groups. In order to analyze the light cur…
OGLE-2016-BLG-0168 Binary Microlensing Event: Prediction and Confirmation of the Micorlens Parallax Effect from Space-based Observation
I. -G. Shin, A. Udalski, J. C. Yee +32
The microlens parallax is a crucial observable for conclusively identifying the nature of lens systems in microlensing events containing or composed of faint (even dark) astronomic…
An Earth-mass Planet in a 1-AU Orbit around an Ultracool Dwarf
Y. Shvartzvald, J. C. Yee, S. Calchi Novati +22
We combine and ground-based KMTNet microlensing observations to identify and precisely measure an Earth-mass () planet OGLE-2016-BLG-1195Lb…
OGLE-2015-BLG-1482L: the first isolated low-mass microlens in the Galactic bulge
S. -J. Chung, W. Zhu, A. Udalski +35
We analyze the single microlensing event OGLE-2015-BLG-1482 simultaneously observed from two ground-based surveys and from \textit{Spitzer}. The \textit{Spitzer} data exhibit finit…
Korea Microlensing Telescope Network Microlensing Events from 2015: Event-Finding Algorithm, Vetting, and Photometry
D. -J. Kim, H. -W. Kim, K. -H. Hwang +15
We present microlensing events in the 2015 Korea Microlensing Telescope Network (KMTNet) data and our procedure for identifying these events. In particular, candidates were detecte…
Toward a Galactic Distribution of Planets. I. Methodology & Planet Sensitivities of the 2015 High-Cadence Spitzer Microlens Sample
Wei Zhu, A. Udalski, S. Calchi Novati +35
We analyze an ensemble of microlensing events from the 2015 Spitzer microlensing campaign, all of which were densely monitored by ground-based high-cadence survey teams. The simult…
