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…

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…
