OGLE-2015-BLG-1395Lb: A Cold Sub-Saturn Mass Planet Orbiting an M Dwarf
Andrew A. Cole, Joshua W. Blackman, Jean-Philippe Beaulieu +75
We present an analysis of the high-magnification microlensing event OGLE-2015-BLG-1395 and report the discovery of a sub-Saturn mass companion to the lens. Photometric coverage of…
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…
Roman CCS White Paper: Characterizing the Galactic population of isolated black holes
Casey Y. Lam, Natasha Abrams, Jeff Andrews +34
Although there are estimated to be 100 million isolated black holes (BHs) in the Milky Way, only one has been found so far, resulting in significant uncertainty about their propert…
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-…
Terrestrial and Neptune mass free-floating planet candidates from the MOA-II 9-year Galactic Bulge survey
Naoki Koshimoto, Takahiro Sumi, David P. Bennett +28
We report the discoveries of low-mass free-floating planet (FFP) candidates from the analysis of 2006-2014 MOA-II Galactic bulge survey data. In this dataset, we found 6,111 microl…
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…
OGLE-2018-BLG-0584 and KMT-2018-BLG-2119: two microlensing events with two lens masses and two source stars
Cheongho Han, Andrzej Udalski, Youn Kil Jung +34
We conduct a systematic investigation of the microlensing data collected during the previous observation seasons for the purpose of reanalyzing anomalous lensing events with no sug…
Chemical evolution of the Galactic bulge as traced by microlensed dwarf and subgiant stars. VI. Age and abundance structure of the stellar populations in the central sub-kpc of the Milky Way
T. Bensby, S. Feltzing, A. Gould +29
We present a detailed elemental abundance study of 90 F and G dwarf, turn-off and subgiant stars in the Galactic bulge. Based on high-resolution spectra acquired during gravitation…
