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…

Spitzer Phase Curves of KELT-1b and the Signatures of Nightside Clouds in Thermal Phase Observations

Thomas G. Beatty, Mark S. Marley, B. Scott Gaudi +3

We observed two full orbital phase curves of the transiting brown dwarf KELT-1b, at 3.6um and 4.5um, using the Spitzer Space Telescope. Combined with previous eclipse data from Bea…

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…

A-type Stars, the Destroyers of Worlds: The lives and deaths of Jupiters in evolving stellar binaries

Alexander P. Stephan, Smadar Naoz, B. Scott Gaudi

Hot Jupiters (HJs), gas giant planets orbiting their host stars with periods on the order of days, commonly occur in the Galaxy, including relatively massive ( ,…
