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…

Mysterious Dust-emitting Object Orbiting TIC 400799224

Brian P. Powell, Veselin Kostov, Saul Rappaport +24

We report the discovery of a unique object of uncertain nature -- but quite possibly a disintegrating asteroid or minor planet -- orbiting one star of the widely separated binary T…

New Giant Planet beyond the Snow Line for an Extended MOA Exoplanet Microlens Sample

Clément Ranc, David P. Bennett, Richard K. Barry +28

Characterizing a planet detected by microlensing is hard if the planetary signal is weak or the lens-source relative trajectory is far from caustics. However, statistical analyses…

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…

TIC 454140642: A Compact, Coplanar, Quadruple-lined Quadruple Star System Consisting of Two Eclipsing Binaries

Veselin B. Kostov, Brian P. Powell, Guillermo Torres +30

We report the discovery of a compact, coplanar, quadruply-lined, eclipsing quadruple star system from TESS data, TIC 454140642, also known as TYC 0074-01254-1. The target was first…

MOA-2006-BLG-074: recognizing xallarap contaminants in planetary microlensing

P. Rota, Y. Hirao, V. Bozza +23

MOA-2006-BLG-074 was selected as one of the most promising planetary candidates in a retrospective analysis of the MOA collaboration: its asymmetric high-magnification peak can be…

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…

TIC 172900988: A Transiting Circumbinary Planet Detected in One Sector of TESS Data

Veselin B. Kostov, Brian P. Powell, Jerome A. Orosz +86

We report the first discovery of a transiting circumbinary planet detected from a single sector of TESS data. During Sector 21, the planet TIC 172900988b transited the primary star…

Systematic KMTNet Planetary Anomaly Search, Paper I: OGLE-2019-BLG-1053Lb, A Buried Terrestrial Planet

Weicheng Zang, Kyu-Ha Hwang, Andrzej Udalski +69

In order to exhume the buried signatures of "missing planetary caustics" in the KMTNet data, we conducted a systematic anomaly search to the residuals from point-source point-lens…

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…

Identifying Planetary Transit Candidates in TESS Full-Frame Image Light Curves via Convolutional Neural Networks

Greg Olmschenk, Stela Ishitani Silva, Gioia Rau +8

The Transiting Exoplanet Survey Satellite (TESS) mission measured light from stars in ~75% of the sky throughout its two year primary mission, resulting in millions of TESS 30-minu…
