An unusually large gaseous transit in a debris disc
Daniela P. Iglesias, Johan Olofsson, Amelia Bayo +9
We present the detection of an unusually large transient gas absorption in several ionized species in the debris disc star HD 37306 using high-resolution optical spectra. We have b…
EPIC247098361b: a transiting warm Saturn on an eccentric days orbit around a star
Rafael Brahm, Néstor Espinoza, Andrés Jordán +12
We report the discovery of EPIC247098361b using photometric data of the Kepler K2 satellite coupled with ground-based spectroscopic observations. EPIC247098361b has a mass of M$_{P…
An HST survey of 33 T8 to Y1 brown dwarfs: NIR photometry and multiplicity of the coldest isolated objects
Clemence Fontanive, Luigi R. Bedin, Matthew De Furio +5
We present results from a Hubble Space Telescope imaging search for low-mass binary and planetary companions to 33 nearby brown dwarfs with spectral types of T8-Y1. Our survey prov…
A Novel Survey for Young Substellar Objects with the W-band filter III: Searching for very low mass brown dwarfs in Serpens South and Serpens Core
Sophie Dubber, Beth Biller, Katelyn Allers +10
We present CFHT photometry and IRTF spectroscopy of low-mass candidate members of Serpens South and Serpens Core (430 pc, 0.5 Myr), identified using a novel combination…
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…
An independent discovery of two hot Jupiters from the K2 mission
Rafael Brahm, MatÃas 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 $…
A wide planetary-mass companion to a young low-mass brown dwarf in Ophiuchus
Clemence Fontanive, Katelyn N. Allers, Blake Pantoja +6
We present the discovery of a planetary-mass companion to CFHTWIR-Oph 98, a low-mass brown dwarf member of the young Ophiuchus star-forming region, with a wide 200-au separation (1…
Discovery and Validation of a High-Density sub-Neptune from the K2 Mission
Néstor Espinoza, Rafael Brahm, Andrés Jordán +12
We report the discovery of BD+20594b, a high density sub-Neptune exoplanet, made using photometry from Campaign 4 of the two-wheeled Kepler (K2) mission, ground-based radial veloci…
EPIC 201498078b: A low density Super Neptune on an eccentric orbit
Rafael Brahm, Nestor Espinoza, Markus Rabus +15
We report the discovery of EPIC 201498078b, which was first identified as a planetary candidate from Kepler K2 photometry of Campaign 14, and whose planetary nature and orbital par…
