HATS-54b-HATS-58Ab: five new transiting hot Jupiters including one with a possible temperate companion
Néstor Espinoza, Joel D. Hartman, Gaspar Á. Bakos +18
We report the discovery by the HATSouth project of 5 new transiting hot Jupiters (HATS-54b through HATS-58Ab). HATS-54b, HATS-55b and HATS-58Ab are prototypical short period ($P =…
Constraining the period of the ringed secondary companion to the young star J1407 with photographic plates
R. T. Mentel, M. A. Kenworthy, D. A. Cameron +13
Context. The 16 Myr old star 1SWASP J140747.93-394542.6 (V1400 Cen) underwent a series of complex eclipses in May 2007, interpreted as the transit of a giant Hill sphere filling de…
Photodynamical analysis of the triply eclipsing hierarchical triple system EPIC 249432662
T. Borkovits, S. Rappaport, T. Kaye +16
Using Campaign 15 data from the K2 mission, we have discovered a triply-eclipsing triple star system: EPIC 249432662. The inner eclipsing binary system has a period of 8.23 days, w…
HATS-60b - HATS-69b: Ten Transiting Planets From HATSouth
J. D. Hartman, G. A. Bakos, D. Bayliss +27
We report the discovery of ten transiting extrasolar planets by the HATSouth survey. The planets range in mass from the Super-Neptune HATS-62b, with , to the S…

Kristo Ment, Jason A. Dittmann, Nicola Astudillo-Defru +27
LHS 1140 is a nearby mid-M dwarf known to host a temperate rocky super-Earth (LHS 1140 b) on a 24.737-day orbit. Based on photometric observations by MEarth and Spitzer as well as…
A Planetary Microlensing Event with an Unusually Red Source Star: MOA-2011-BLG-291
David P. Bennett, Andrzej Udalski, Ian A. Bond +43
We present the analysis of planetary microlensing event MOA-2011-BLG-291, which has a mass ratio of and a source star that is redder (or brighter) than…
