Phase Curves of Hot Neptune LTT 9779b Suggest a High-Metallicity Atmosphere
Ian J. M. Crossfield, Diana Dragomir, Nicolas B. Cowan +20
Phase curve measurements provide a global view of the composition, thermal structure, and dynamics of exoplanet atmospheres. Although most of the dozens of phase curve measurements…
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…
Optical to near-infrared transmission spectrum of the warm sub-Saturn HAT-P-12b
Ian Wong, Björn Benneke, Peter Gao +12
We present the transmission spectrum of HAT-P-12b through a joint analysis of data obtained from the Hubble Space Telescope Space Telescope Imaging Spectrograph (STIS) and Wide Fie…
Strong Near-Infrared Spectral Variability of the Young Cloudy L Dwarf Companion VHS J1256-1257 b
Brendan P. Bowler, Yifan Zhou, Caroline V. Morley +4
Rotationally-modulated variability of brown dwarfs and giant planets provides unique information about their surface brightness inhomogeneities, atmospheric circulation, cloud evol…
Spectral Variability of VHS J1256-1257 b from 1 to 5 m
Yifan Zhou, Brendan P. Bowler, Caroline V. Morley +4
Multi-wavelength time-resolved observations of rotationally modulated variability from brown dwarfs and giant exoplanets are the most effective method for constraining their hetero…
Smaller than expected bright-spot offsets in Spitzer phase curves of the hot Jupiter Qatar-1b
Dylan Keating, Kevin B. Stevenson, Nicolas B. Cowan +16
We present \textit{Spitzer} full-orbit thermal phase curves of the hot Jupiter Qatar-1b, a planet with the same equilibrium temperature---and intermediate surface gravity and orbit…
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…
