Faint source star planetary microlensing: the discovery of the cold gas giant planet OGLE-2014-BLG-0676Lb
N. J. Rattenbury, D. P. Bennett, T. Sumi +85
We report the discovery of a planet --- OGLE-2014-BLG-0676Lb --- via gravitational microlensing. Observations for the lensing event were made by the MOA, OGLE, Wise, RoboNET/LCOGT,…
K2-113b: A dense hot-Jupiter transiting a solar analogue
Néstor Espinoza, Markus Rabus, Rafael Brahm +8
We present the discovery of K2-113b, a dense hot-Jupiter discovered using photometry from Campaign 8 of the Kepler-2 (K2) mission and high-resolution spectroscopic follow up obtain…
HATS-31b Through HATS-35b: Five Transiting Hot Jupiters Discovered by the HATSouth Survey
M. de Val-Borro, G. Á. Bakos, R. Brahm +24
We report the discovery of five new transiting hot Jupiter planets discovered by the HATSouth survey: HATS-31b through HATS-35b. These planets orbit moderately bright stars with V…
HATS-22b, HATS-23b and HATS-24b: Three new transiting Super-Jupiters from the HATSouth Project
Joao Bento, Brian Schmidt, Joel Hartman +22
We report the discovery of three moderately high-mass transiting hot Jupiters from the HATSouth survey: HATS-22b, HATS-23b and HATS-24b. These planets add to the numbers of known p…
HATS-19b, HATS-20b, HATS-21b: Three Transiting Hot-Saturns Discovered by the HATSouth Survey
W. Bhatti, G. Á. Bakos, J. D. Hartman +24
We report the discovery by the HATSouth exoplanet survey of three hot-Saturn transiting exoplanets: HATS-19b, HATS-20b, and HATS-21b. The planet host HATS-19 is a slightly evolved…
First simultaneous microlensing observations by two space telescopes: & reveal a brown dwarf in event OGLE-2015-BLG-1319
Y. Shvartzvald, Z. Li, A. Udalski +90
Simultaneous observations of microlensing events from multiple locations allow for the breaking of degeneracies between the physical properties of the lensing system, specifically…
HATS-18 b: An Extreme Short--Period Massive Transiting Planet Spinning Up Its Star
Kaloyan M. Penev, Joel D. Hartman, Gaspar A. Bakos +19
We report the discovery by the HATSouth network of HATS-18 b: a 1.980 +/- 0.077 Mj, 1.337 +0.102 -0.049 Rj planet in a 0.8378 day orbit, around a solar analog star (mass 1.037 +/-…
HATS-25b through HATS-30b: A Half-dozen New Inflated Transiting Hot Jupiters from the HATSouth Survey
N. Espinoza, D. Bayliss, J. D. Hartman +19
We report six new inflated hot Jupiters (HATS-25b through HATS-30b) discovered using the HATSouth global network of automated telescopes. The planets orbit stars with magnitude…
High-resolution Imaging of Transiting Extrasolar Planetary systems (HITEP). I. Lucky imaging observations of 101 systems in the southern hemisphere
D. F. Evans, J. Southworth, P. F. L. Maxted +33
(abridged) Context. Wide binaries are a potential pathway for the formation of hot Jupiters. The binary fraction among host stars is an important discriminator between competing fo…
HATS-11b and HATS-12b: Two transiting Hot Jupiters orbiting sub-solar metallicity stars selected for the K2 Campaign 7
M. Rabus, A. Jordán, J. D. Hartman +21
We report the discovery of two transiting extrasolar planets from the HATSouth survey. HATS-11, a V=14.1 G0-star shows a periodic 12.9 mmag dip in its light curve every 3.6192 days…
An independent discovery of two hot Jupiters from the K2 mission
Rafael Brahm, Matías Jones, Néstor Espinoza +9
We report the discovery of two hot Jupiters using photometry from Campaigns 4 and 5 of the two-wheeled Kepler (K2) mission. K2-30b has a mass of , a radius of $…
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…
