The Star Blended with the MOA-2008-BLG-310 Source Is Not the Exoplanet
Host Star
, 2017 High resolution Hubble Space Telescope (HST) image analysis of the
MOA-2008-BLG-310 microlens system indicates that the excess flux at the
location of the source found in the discovery paper cannot primarily be due to
the lens star because it does not ...Anderson, J., Batista, V., Beaulieu, J. P., Bennett, D. P., Bhattacharya, A., Bond, I. A., Fouque, P., Gould, A., Marquette, J. B., Pogge, R. +9 morecore +3 more sourcesMass Production of 2023 KMTNet Microlensing Planets. I. Low Mass Ratio
The Astronomical JournalWe initiate the systematic search for planets in the 2023 data of the Korea Microlensing Telescope Network (KMTNet), focusing on those planets found by the KMTNet AnomalyFinder with low preliminary estimates of the mass ratio, q Yoon-Hyun Ryu, Andrzej Udalski, Hongjing Yang, Kyu-Ha Hwang, Weicheng Zang, Yang Huang, Andrew Gould, Michael D.

The Astronomical JournalWe report discovering an exoplanet from following up a microlensing event alerted by Gaia. The event Gaia22dkv is toward a disk source rather than the traditional bulge microlensing fields.

Provisional WFIRST Microlensing Survey Field
, 2019 We present the analysis of the microlensing event OGLE-2015-BLG-1670,
detected in a high-extinction field, very close to the Galactic plane. Due to
the dust extinction along the line of sight, this event was too faint to be
detected before it reached the :, :, :, Abe, Fumio, Albrow, Michael D., Barry, Richard K., Bennett, David P., Bhattacharya, Aparna, Bond, Ian A., Cha, Sang-Mok, Chung, Sun-Ju, Collaboration, The KMTNet, Collaboration, The MOA, Collaboration, The OGLE, Donachie, Martin, Fukui, Akihiko, Gould, Andrew, Han, Cheongho, Hirao, Yuki, Hwang, Kyu-Ha, Itow, Yoshitaka, Jung, Youn-Kil, Kawasaki, Kohei, Kim, Dong-Jin, Kim, Hyoun-Woo, Kim, Seung-Lee, Kondo, Iona, Koshimoto, Naoki, Kozłowski, Szymon, Lee, Chung-Uk, Lee, Dong-Joo, Lee, Yong-Seok, Li, Man Cheung Alex, Matsubara, Yutaka, Miyazaki, Shota, Mróz, Przemek, Muraki, Yasushi, Nagakane, Masayuki, Park, Byeong-Gon, Pietrukowicz, Paweł, Pogge, Richard W., Poleski, Radosław, Ranc, Clément, Rattenbury, Nicholas J., Ryu, Yoon-Hyun, Shin, In-Gu, Shvartzvald, Yossi, Skowron, Jan, Soszyński, Igor, Suematsu, Haruno, Sullivan, Denis J., Sumi, Takahiro, Suzuki, Daisuke, Szymański, Michał K., Tristram, Paul J., Udalski, Andrzej, Ulaczyk, Krzysztof, Yee, Jennifer C., Yonehara, Atsunori, Zang, Weicheng, Zhu, Wei +60 morecore +1 more sourceKMT-2023-BLG-2669: Ninth Free-floating Planet Candidate with θ E Measurements
The Astronomical JournalWe report a free-floating planet (FFP) candidate identified from the analysis of the microlensing event KMT-2023-BLG-2669. The lensing light curve is characterized by a short duration (≲3 days) and a small amplitude (≲0.7 mag).
