OGLE-2014-BLG-0319: A Sub-Jupiter-Mass Planetary Event Encountered Degeneracy with Different Mass Ratios and Lens-Source Relative Proper Motions
Shota Miyazaki, Daisuke Suzuki, Andrzej Udalski +36
We report the discovery of a sub-Jovian-mass planet, OGLE-2014-BLG-0319Lb. The characteristics of this planet will be added into a future extended statistical analysis of the Micro…
Single-lens mass measurement in the high-magnification microlensing event Gaia19bld located in the Galactic disc
K. A. Rybicki, Ł. Wyrzykowski, E. Bachelet +66
We present the photometric analysis of Gaia19bld, a high-magnification () microlensing event located in the southern Galactic plane, which exhibited finite source and m…
Using Source Proper Motion to Validate Terrestrial Parallax: OGLE-2019-BLG-1058
In-Gu Shin, Jennifer C. Yee, Kyu-Ha Hwang +30
We show that because the conditions for producing terrestrial microlens parallax (TPRX; i.e., a nearby disk lens) will also tend to produce a large lens-source relative proper moti…
Kepler K2 Campaign 9: I. Candidate short-duration events from the first space-based survey for planetary microlensing
I. McDonald, E. Kerins, R. Poleski +6
We present the first short-duration candidate microlensing events from the Kepler K2 mission. From late April to early July 2016, Campaign 9 of K2 obtained high temporal cadence ob…
Systematic KMTNet Planetary Anomaly Search, Paper II: Six New Mass-ratio Planets
Kyu-Ha Hwang, Weicheng Zang, Andrew Gould +62
We apply the automated AnomalyFinder algorithm of Paper I (Zang et al. 2021b) to 2018-2019 light curves from the covered by the six KMTNet prime fields, wi…
Wide-orbit exoplanets are common. Analysis of nearly 20 years of OGLE microlensing survey data
R. Poleski, J. Skowron, P. Mróz +8
We use nearly 20 years of photometry obtained by the OGLE survey to measure the occurrence rate of wide-orbit (or ice giant) microlensing planets, i.e., with separations from ~5 AU…
KMT-2019-BLG-1715: planetary microlensing event with three lens masses and two source stars
Cheongho Han, Andrzej Udalski, Doeone Kim +61
We investigate the gravitational microlensing event KMT-2019-BLG-1715, of which light curve shows two short-term anomalies from a caustic-crossing binary-lensing light curve: one w…
OGLE-2018-BLG-1428Lb: a Jupiter-mass planet beyond the snow line of a dwarf star
Yun-Hak Kim, Sun-Ju Chung, Andrej Udalski +29
We present the analysis of the microlensing event OGLE-2018-BLG-1428, which has a short-duration ( day) caustic-crossing anomaly. The event was caused by a planetary lens s…
OGLE-2018-BLG-0567Lb and OGLE-2018-BLG-0962Lb: Two Microlensing Planets through Planetary-Caustic Channel
Youn Kil Jung, Cheongho Han, Andrzej Udalski +29
We present the analyses of two microlensing events, OGLE-2018-BLG-0567 and OGLE-2018-BLG-0962. In both events, the short-lasting anomalies were densely and continuously covered by…
Progenitor, environment, and modelling of the interacting transient, AT 2016jbu (Gaia16cfr)
S. J. Brennan, M. Fraser, J. Johansson +67
We present the bolometric lightcurve, identification and analysis of the progenitor candidate, and preliminary modelling of AT2016jbu (Gaia16cfr). We find a progenitor consistent w…
Photometric and spectroscopic evolution of the interacting transient AT 2016jbu (Gaia16cfr)
S. J. Brennan, M. Fraser, J. Johansson +68
We present the results from a high cadence, multi-wavelength observation campaign of AT 2016jbu (aka Gaia16cfr), an interacting transient. This dataset complements the current lite…
KMT-2019-BLG-0371 and the Limits of Bayesian Analysis
Yun Hak Kim, Sun-Ju Chung, Jennifer C. Yee +54
We show that the perturbation at the peak of the light curve of microlensing event KMT-2019-BLG-0371 is explained by a model with a mass ratio between the host star and planet of $…
