OGLE-2018-BLG-1185b : A Low-Mass Microlensing Planet Orbiting a Low-Mass Dwarf

Iona Kondo, Jennifer C. Yee, David P. Bennett +94

We report the analysis of planetary microlensing event OGLE-2018-BLG-1185, which was observed by a large number of ground-based telescopes and by the Space Telescope. The…

Binarity as the Origin of Long Secondary Periods in Red Giant Stars

I. Soszyński, A. Olechowska, M. Ratajczak +13

Long secondary periods (LSPs), observed in a third of pulsating red giant stars, are the only unexplained type of large-amplitude stellar variability known at this time. Here we sh…

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-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…

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 $…

OGLE-2019-BLG-0960Lb: The Smallest Microlensing Planet

Jennifer C. Yee, Weicheng Zang, Andrzej Udalski +80

We report the analysis of OGLE-2019-BLG-0960, which contains the smallest mass-ratio microlensing planet found to date (q = 1.2--1.6 x 10^{-5} at 1-sigma). Although there is substa…
