Radii of 88 M Subdwarfs and Updated Radius Relations for Low-Metallicity M Dwarf Stars
Aurora Y. Kesseli, J. Davy Kirkpatrick, Sergio B. Fajardo-Acosta +9
M subdwarfs are low-metallicity M dwarfs that typically inhabit the halo population of the Galaxy. Metallicity controls the opacity of stellar atmospheres; in metal poor stars, hyd…
WFIRST Exoplanet Mass Measurement Method Finds a Planetary Mass of for OGLE-2012-BLG-0950Lb
A. Bhattacharya, J. P. Beaulieu, D. P. Bennett +13
We present the analysis of the simultaneous high resolution images from the {\it Hubble Space Telescope} and Keck Adaptive Optics system of the planetary event OGLE-2012-BLG-0950 t…
KMT-2016-BLG-2052L: Microlensing Binary Composed of M Dwarfs Revealed from a Very Long Time-scale Event
Cheongho Han, Youn Kil Jung, Yossi Shvartzvald +26
We present the analysis of a binary microlensing event KMT-2016-BLG-2052, for which the lensing-induced brightening of the source star lasted for 2 seasons. We determine the lens m…
Microlensing Parallax for OGLE-2017-BLG-0896 Reveals a Counter-Rotating Low-Mass Brown Dwarf
Yossi Shvartzvald, Jennifer C. Yee, Jan Skowron +63
The kinematics of isolated brown dwarfs in the Galaxy, beyond the solar neighborhood, is virtually unknown. Microlensing has the potential to probe this hidden population, as it ca…
Spitzer Opens New Path to Break Classic Degeneracy for Jupiter-Mass Microlensing Planet OGLE-2017-BLG-1140Lb
S. Calchi Novati, J. Skowron, Y. K. Jung +36
We analyze the combined Spitzer and ground-based data for OGLE-2017-BLG-1140 and show that the event was generated by a Jupiter-class planet orbiting…
UKIRT-2017-BLG-001Lb: A giant planet detected through the dust
Y. Shvartzvald, S. Calchi Novati, B. S. Gaudi +8
We report the discovery of a giant planet in event UKIRT-2017-BLG-001, detected by the UKIRT microlensing survey. The mass ratio between the planet and its host is $q=1.50_{-0.14}^…
