MOA 2011-BLG-028Lb: a Neptune-mass Microlensing Planet in the Galactic Bulge
J. Skowron, A. Udalski, R. Poleski +35
We present the discovery of a Neptune-mass planet orbiting a 0.8 +- 0.3 M_Sun star in the Galactic bulge. The planet manifested itself during the microlensing event MOA 2011-BLG-02…
Campaign 9 of the Mission: Observational Parameters, Scientific Drivers, and Community Involvement for a Simultaneous Space- and Ground-based Microlensing Survey
Calen B. Henderson, Radosław Poleski, Matthew Penny +118
's Campaign 9 (C9) will conduct a 3.7 deg survey toward the Galactic bulge from 7/April through 1/July of 2016 that will leverage the spatial separation between…
The First Neptune Analog or Super-Earth with Neptune-like Orbit: MOA-2013-BLG-605Lb
T. Sumi, A. Udalski, D. P. Bennett +46
We present the discovery of the first Neptune analog exoplanet or super-Earth with Neptune-like orbit, MOA-2013-BLG-605Lb. This planet has a mass similar to that of Neptune or a su…
Red noise versus planetary interpretations in the microlensing event OGLE-2013-BLG-446
E. Bachelet, D. M. Bramich, C. Han +98
For all exoplanet candidates, the reliability of a claimed detection needs to be assessed through a careful study of systematic errors in the data to minimize the false positives r…
MOA-2010-BLG-353Lb A Possible Saturn Revealed
N. J. Rattenbury, D. P. Bennett, T. Sumi +30
We report the discovery of a possible planet in microlensing event MOA-2010-BLG-353. This event was only recognised as having a planetary signal after the microlensing event had fi…
The frequency of snowline-region planets from four-years of OGLE-MOA-Wise second-generation microlensing
Y. Shvartzvald, D. Maoz, A. Udalski +35
We present a statistical analysis of the first four seasons from a "second-generation" microlensing survey for extrasolar planets, consisting of near-continuous time coverage of 8…
Spitzer Parallax of OGLE-2015-BLG-0966: A Cold Neptune in the Galactic Disk
R. A. Street, A. Udalski, S. Calchi Novati +106
We report the detection of a Cold Neptune m_planet=21+/-2MEarth orbiting a 0.38MSol M dwarf lying 2.5-3.3 kpc toward the Galactic center as part of a campaign combining ground-base…
MOA-2007-BLG-197: Exploring the brown dwarf desert
C. Ranc, A. Cassan, M. D. Albrow +48
We present the analysis of MOA-2007-BLG-197Lb, the first brown dwarf companion to a Sun-like star detected through gravitational microlensing. The event was alerted and followed-up…
