Bayesian analysis of Juno/JIRAM's NIR observations of Europa
Ishan Mishra, Nikole Lewis, Jonathan Lunine +4
Juno spacecraft's spectrometer JIRAM recently observed the moon Europa in the 2-5 μm wavelength region. Here we present analysis of the average spectrum of a set of observations ne…
Evidence of a Clear Atmosphere for WASP-62b: the Only Known Transiting Gas Giant in the JWST Continuous Viewing Zone
Munazza K. Alam, Mercedes Lopez-Morales, Ryan J. MacDonald +12
Exoplanets with cloud-free, haze-free atmospheres at the pressures probed by transmission spectroscopy represent a valuable opportunity for detailed atmospheric characterization an…
Into the UV: The Atmosphere of the Hot Jupiter HAT-P-41b Revealed
Nikole K. Lewis, Hannah R. Wakeford, Ryan J. MacDonald +19
For solar-system objects, ultraviolet spectroscopy has been critical in identifying sources for stratospheric heating and measuring the abundances of a variety of hydrocarbon and s…
ACCESS: Confirmation of no potassium in the atmosphere of WASP-31b
Chima D. McGruder, Mercedes Lopez-Morales, Nestor Espinoza +12
We present a new optical (400-950nm) transmission spectrum of the hot Jupiter WASP-31b (M=0.48 MJ; R= 1.54 RJ; P=3.41 days), obtained by combining four transits observations. These…
The White Dwarf Opportunity: Robust Detections of Molecules in Earth-like Exoplanet Atmospheres with the James Webb Space Telescope
Lisa Kaltenegger, Ryan J. MacDonald, Thea Kozakis +4
The near-term search for life beyond the solar system currently focuses on transiting planets orbiting small M dwarfs, and the challenges of detecting signs of life in their atmosp…
Haze Formation in Warm H2-rich Exoplanet Atmospheres
Chao He, Sarah M. Horst, Nikole K. Lewis +8
New observing capabilities coming online over the next few years will provide opportunities for characterization of exoplanet atmospheres. However, clouds/hazes could be present in…
