Clouds in the atmosphere of the super-Earth exoplanet GJ 1214b
Laura Kreidberg, Jacob L. Bean, Jean-Michel Désert +7
Recent surveys have revealed that planets intermediate in size between Earth and Neptune ("super-Earths") are among the most common planets in the Galaxy. Atmospheric studies are t…
The Solar Neighborhood XXX: Fomalhaut C
Eric E. Mamajek, Jennifer L. Bartlett, Andreas Seifahrt +11
LP 876-10 is a nearby active M4 dwarf in Aquarius at a distance of 7.6 pc. The star is a new addition to the 10-pc census, with a parallax measured via the Research Consortium on N…
Water Absorption from Gas Very Near the Massive Protostar AFGL 2136 IRS 1
Nick Indriolo, D. A. Neufeld, A. Seifahrt +1
We present ground-based observations of the nu_1 and nu_3 fundamental bands of H2O toward the massive protostar AFGL 2136 IRS 1, identifying absorption features due to 47 different…
The Curious Case of Glass I: High Ionization and Variability of Different Types
Andrew J. Kruger, Matthew J. Richter, John S. Carr +4
Our Spitzer IRS observation of the infrared companion Glass Ib revealed fine structure emission with high ionization ([NeIII]/[NeII]=2.1 and [SIV]/[SIII]=0.6) that indicates the ga…
Transmission Spectroscopy of the Hot-Jupiter WASP-12b from 0.7 to 5 microns
Kevin B. Stevenson, Jacob L. Bean, Andreas Seifahrt +5
Since the first report of a potentially non-solar carbon-to-oxygen ratio (C/O) in its dayside atmosphere, the highly irradiated exoplanet WASP-12b has been under intense scrutiny a…
Ground-Based Transit Spectroscopy of the Hot-Jupiter WASP-19b in the Near-Infrared
Jacob L. Bean, Jean-Michel Désert, Andreas Seifahrt +4
We present ground-based measurements of the transmission and emission spectra of the hot-Jupiter WASP-19b in nine spectroscopic channels from 1.25 to 2.35 microns. The measurements…
