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…
TESS full orbital phase curve of the WASP-18b system
Avi Shporer, Ian Wong, Chelsea X. Huang +18
We present a visible-light full orbital phase curve of the transiting planet WASP-18b measured by the TESS Mission. The phase curve includes the transit, secondary eclipse, and sin…
Retrieving Temperatures and Abundances of Exoplanet Atmospheres with High-Resolution Cross-Correlation Spectroscopy
Matteo Brogi, Michael R Line
Hi-resolution spectroscopy (R > 25,000) has recently emerged as one of the leading methods to detect atomic and molecular species in the atmospheres of exoplanets. However, it has…
Measuring the D/H Ratios of Exoplanets and Brown Dwarfs
Caroline V. Morley, Andrew J. Skemer, Brittany E. Miles +5
The relative abundance of deuterium and hydrogen is a potent tracer of planet formation and evolution. Jupiter and Saturn have protosolar atmospheric D/H ratios, a relic of substan…
Ground- and Space-based Detection of the Thermal Emission Spectrum of the Transiting Hot Jupiter KELT-2Ab
Danielle Piskorz, Cam Buzard, Michael R. Line +9
We describe the detection of water vapor in the atmosphere of the transiting hot Jupiter KELT-2Ab by treating the star-planet system as a spectroscopic binary with high-resolution,…
The Influence of H2O Pressure Broadening in High Metallicity Exoplanet Atmospheres
Ehsan Gharib-Nezhad, Michael R. Line
Planet formation models suggest broad compositional diversity in the sub-Neptune/super-Earth regime, with a high likelihood for large atmospheric metal content (> 100 x Solar). Wit…
