OGLE-2017-BLG-0448Lb: A Low Mass-Ratio Wide-Orbit Microlensing Planet?
Ruocheng Zhai, Radosław Poleski, Weicheng Zang +38
The gravitational microlensing technique is most sensitive to planets in a Jupiter-like orbit and has detected more than 200 planets. However, only a few wide-orbit () micro…
OGLE-2019-BLG-1180Lb: Discovery of a Wide-orbit Jupiter-mass Planet around a Late-type Star
Sun-Ju Chung, Andrzej Udalski, Jennifer C. Yee +30
We report on the discovery and analysis of the planetary microlensing event OGLE-2019-BLG-1180 with a planet-to-star mass ratio . The event OGLE-2019-BLG-1180 has una…
KMT-2023-BLG-1431Lb: A New Microlensing Planet from a Subtle Signature
Aislyn Bell, Jiyuan Zhang, Youn Kil Jung +70
The current studies of microlensing planets are limited by small number statistics. Follow-up observations of high-magnification microlensing events can efficiently form a statisti…
Candidates for Transiting Planets in OGLE-IV Galactic Bulge Fields
M. J. Mróz, P. Pietrukowicz, R. Poleski +13
We present results of a search for transiting exoplanets in 10-yr long photometry with thousands of epochs taken in the direction of the Galactic bulge. This photometry was collect…
The OGLE Collection of Variable Stars. Over 15 000 Delta Scuti Stars in the Large Magellanic Cloud
I. Soszyński, P. Pietrukowicz, A. Udalski +12
We present the OGLE collection of delta Scuti stars in the Large Magellanic Cloud and in its foreground. Our dataset encompasses a total of 15 256 objects, constituting the largest…
Blue Large-Amplitude Pulsators and Other Short-Period Variable Stars in the OGLE-IV Galactic Disk Fields
J. Borowicz, P. Pietrukowicz, P. Mróz +12
Blue Large-Amplitude Pulsators (BLAPs) form a mysterious class of variable stars with typical periods of tens of minutes and amplitudes above 0.1 mag. In this work, we present resu…
Systematic KMTNet Planetary Anomaly Search. X. Complete Sample of 2017 Prime-Field Planets
Yoon-Hyun Ryu, Andrzej Udalski, Jennifer C. Yee +38
We complete the analysis of planetary candidates found by the KMT AnomalyFinder for the 2017 prime fields that cover . We report 3 unambiguous planets: OGLE-2…
OGLE-2019-BLG-0825: Constraints on the Source System and Effect on Binary-lens Parameters arising from a Five Day Xallarap Effect in a Candidate Planetary Microlensing Event
Yuki K. Satoh, Naoki Koshimoto, David P. Bennett +86
We present an analysis of microlensing event OGLE-2019-BLG-0825. This event was identified as a planetary candidate by preliminary modeling. We find that significant residuals from…
Systematic KMTNet Planetary Anomaly Search. IX. Complete Sample of 2016 Prime-Field Planets
In-Gu Shin, Jennifer C. Yee, Weicheng Zang +58
As a part of the ``Systematic KMTNet Planetary Anomaly Search" series, we report five new planets (namely, OGLE-2016-BLG-1635Lb, MOA-2016-BLG-532Lb, KMT-2016-BLG-0625Lb, OGLE-2016-…
Systematic KMTNet Planetary Anomaly Search. VIII. Complete Sample of 2019 Subprime Field Planets
Youn Kil Jung, Weicheng Zang, Hanyue Wang +41
We complete the publication of all microlensing planets (and ``possible planets'') identified by the uniform approach of the KMT AnomalyFinder system in the 21 KMT subprime fields…
OGLE-2017-BLG-1038: A Possible Brown-dwarf Binary Revealed by Spitzer Microlensing Parallax
Amber Malpas, Michael D. Albrow, Jennifer C. Yee +41
We report the analysis of microlensing event OGLE-2017-BLG-1038, observed by the Optical Gravitational Lensing Experiment, Korean Microlensing Telescope Network, and Spitzer telesc…
The OGLE Collection of Variable Stars. Over 2600 Delta Scuti Stars in the Small Magellanic Cloud
I. Soszyński, A. Udalski, J. Skowron +11
We present the first-ever collection of delta Scuti stars found over the entire area of the Small Magellanic Cloud (SMC). The sample consists of 2810 variables of which over 2600 o…
