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 =…
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…
Juliet: a versatile modelling tool for transiting and non-transiting exoplanetary systems
Néstor Espinoza, Diana Kossakowski, Rafael Brahm
Here we present juliet, a versatile tool for the analysis of transits, radial-velocities, or both. juliet is built over many available tools for the modelling of transits, radial-v…
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…
Efficient Joint Sampling of Impact Parameters and Transit Depths in Transiting Exoplanet Light Curves
Néstor Espinoza
When fitting transiting exoplanet lightcurves, it is usually desirable to have ranges and/or priors for the parameters which are to be retrieved that include our degree of knowledg…
HD 1397b: a transiting warm giant planet orbiting a V = 7.8 mag sub-giant star discovered by TESS
Rafael Brahm, Néstor Espinoza, Andrés Jordán +11
We report the discovery of a transiting planet first identified as a candidate in Sector 1 of the Transiting Exoplanet Survey Satellite (TESS), and then confirmed with precision ra…
A Large Ground-Based Observing Campaign of the Disintegrating Planet K2-22b
Knicole D. Colón, George Zhou, Avi Shporer +27
We present 45 ground-based photometric observations of the K2-22 system collected between December 2016 and May 2017, which we use to investigate the evolution of the transit of th…
K2-287b: an Eccentric Warm Saturn transiting a G-dwarf
Andrés Jordán, Rafael Brahm, Néstor Espinoza +23
We report the discovery of K2-287b, a Saturn mass planet orbiting a G-dwarf with a period of days. First uncovered as a candidate using K2 campaign 15 data, follow-u…
HATS-60b - HATS-69b: Ten Transiting Planets From HATSouth

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…
ACCESS: A featureless optical transmission spectrum for WASP-19b from Magellan/IMACS
Néstor Espinoza, Benjamin V. \ Rackham, Andrés Jordán +13
The short period (-day) transiting exoplanet WASP-19b is an exceptional target for transmission spectroscopy studies, due to its relatively large atmospheric scale-height ($\…
