High-Resolution Transit Spectroscopy of Warm Saturns
Emily K. Deibert, Ernst J. W. de Mooij, Ray Jayawardhana +4
We present high-resolution optical transmission spectroscopy of two sub-Saturn mass transiting exoplanets, HAT-P-12b and WASP-69b. With relatively low densities and high atmospheri…
Detection of Helium in the Atmosphere of the Exo-Neptune HAT-P-11b
Megan Mansfield, Jacob L. Bean, Antonija Oklopčić +11
The helium absorption triplet at a wavelength of 10,833 Å has been proposed as a way to probe the escaping atmospheres of exoplanets. Recently this feature was detected for the fir…
Detecting Water In the atmosphere of HR 8799 c with L-band High Dispersion Spectroscopy Aided By Adaptive Optics
Ji Wang, Dimitri Mawet, Jonathan J. Fortney +3
High dispersion spectroscopy of brown dwarfs and exoplanets enables exciting science cases, e.g., mapping surface inhomogeneity and measuring spin rate. Here, we present band o…
Connecting Giant Planet Atmosphere and Interior Modeling: Constraints on Atmospheric Metal Enrichment
Daniel P. Thorngren, Jonathan J. Fortney
Atmospheric characterization through spectroscopic analysis, an essential tool of modern exoplanet science, can benefit significantly from the context provided by interior structur…
The LEECH Exoplanet Imaging Survey: Limits on Planet Occurrence Rates Under Conservative Assumptions
Jordan M. Stone, Andrew J. Skemer, Philip M. Hinz +33
We present the results of the largest (m) direct imaging survey for exoplanets to date, the Large Binocular Telescope Interferometer (LBTI) Exozodi Exoplanet Co…
The direct detection of the irradiated brown dwarf in the white dwarf - brown dwarf binary SDSS J141126.20+200911.1
S. L. Casewell, S. P. Littlefair, S. G. Parsons +3
We have observed the eclipsing, post-common envelope white dwarf-brown dwarf binary, SDSS141126.20+200911.1, in the near-IR with the HAWK-I imager, and present here the first direc…
