A Super-Jupiter Microlens Planet Characterized by High-Cadence KMTNet Microlensing Survey Observations of OGLE-2015-BLG-0954

I. -G. Shin, Y. -H. Ryu, A. Udalski +26

We report the characterization of a massive (m_p=3.9 +- 1.4 M_jup) microlensing planet (OGLE-2015-BLG-0954Lb) orbiting an M dwarf host (M=0.33 +- 0.12 M_sun) at a distance toward t…

Spitzer Observations of OGLE-2015-BLG-1212 Reveal a New Path to Breaking Strong Microlens Degeneracies

V. Bozza, Y. Shvartzvald, A. Udalski +98

Spitzer microlensing parallax observations of OGLE-2015-BLG-1212 decisively breaks a degeneracy between planetary and binary solutions that is somewhat ambiguous when only ground-b…

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…

Mass Measurements of Isolated Objects from Space-based Microlensing

Wei Zhu, S. Calchi Novati, A. Gould +78

We report on the mass and distance measurements of two single-lens events from the 2015 \emph{Spitzer} microlensing campaign. With both finite-source effect and microlens parallax…

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…

Spitzer Microlens Measurement of a Massive Remnant in a Well-Separated Binary

Y. Shvartzvald, A. Udalski, A. Gould +63

We report the detection and mass measurement of a binary lens OGLE-2015-BLG-1285La,b, with the more massive component having (80% probability). A main-sequence…
