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…

Confirmation of water emission in the dayside spectrum of the ultrahot Jupiter WASP-121b

Thomas Mikal-Evans, David K. Sing, Tiffany Kataria +5

We present four new secondary eclipse observations for the ultrahot Jupiter WASP-121b acquired using the Hubble Space Telescope Wide Field Camera 3. The eclipse depth is measured t…

Into the UV: A precise transmission spectrum of HAT-P-41b using Hubble's WFC3/UVIS G280 grism

H. R. Wakeford, D. K. Sing, K. B. Stevenson +8

The ultraviolet-visible wavelength range holds critical spectral diagnostics for the chemistry and physics at work in planetary atmospheres. To date, exoplanet time-series atmosphe…

Non-detection of TiO and VO in the atmosphere of WASP-121b using high-resolution spectroscopy

Stephanie R. Merritt, Neale P. Gibson, Stevanus K. Nugroho +9

Thermal inversions have long been predicted to exist in the atmospheres of ultra-hot Jupiters. However, detection of two species thought to be responsible -- TiO and VO -- remain e…

Detection of Fe I in the atmosphere of the ultra-hot Jupiter WASP-121b, and a new likelihood-based approach for Doppler-resolved spectroscopy

Neale P. Gibson, Stephanie Merritt, Stevanus K. Nugroho +10

High-resolution Doppler-resolved spectroscopy has opened up a new window into the atmospheres of both transiting and non-transiting exoplanets. Here, we present VLT/UVES observatio…
