Secondary eclipses of WASP-18b -- Near Infrared observations with the Anglo Australian Telescope, the Magellan Clay Telescope and the LCOGT network

L. Kedziora-Chudczer, G. Zhou, J. Bailey +6

We present new eclipse observations for one of the hottest "hot Jupiters" WASP-18b, for which previously published data from HST WFC3 and Spitzer have led to radically conflicting…

ACCESS: Ground-based Optical Transmission Spectroscopy of the Hot Jupiter WASP-4b

Alex Bixel, Benjamin V. Rackham, Dániel Apai +6

We present an optical transmission spectrum of the atmosphere of WASP-4b obtained through observations of four transits with Magellan/IMACS. Using a Bayesian approach to atmospheri…

A candidate super-Earth planet orbiting near the snow line of Barnard's star

I. Ribas, M. Tuomi, A. Reiners +60

At a distance of 1.8 parsecs, Barnard's star (Gl 699) is a red dwarf with the largest apparent motion of any known stellar object. It is the closest single star to the Sun, second…

HATS-70b: A 13 Mjup brown dwarf transiting an A star

G. Zhou, G. Á. Bakos, D. Bayliss +23

We report the discovery of HATS-70b, a transiting brown dwarf at the deuterium burning limit. HATS-70b has a mass of Mp=12.9 +1.8/-1.6 Mjup and a radius of Rp=1.384 +0.079/-0.074 R…

HD2685 b: A Hot-Jupiter orbiting an early F-type star detected by TESS

M. I. Jones, R. Brahm, N. Espinoza +40

We report on the confirmation of a transiting giant planet around the relatively hot (Teff = 6801 56 K) star HD2685, whose transit signal was detected in Sector 1 data of the…

Back to "Normal" for the Disintegrating Planet Candidate KIC 12557548 b

Everett Schlawin, Teruyuki Hirano, Hajime Kawahara +5

KIC 12557548 b is first of a growing class of intriguing disintegrating planet candidates, which lose mass in the form of a metal rich vapor that condenses into dust particles. Her…
