  • The Hubble PanCET Program: A Featureless Transmission Spectrum for WASP-29b and Evidence of Enhanced Atmospheric Metallicity on WASP-80b 
    Wong, Ian; Chachan, Yayaati; Knutson, Heather A.; Henry, Gregory W.; Adams, Danica; Kataria, Tiffany; Benneke, Björn; Gao, Peter; Deming, Drake; López-Morales, Mercedes; Sing, David K.; Alam, Munazza K.; Ballester, Gilda E.; Barstow, Joanna K.; Buchhave, Lars A.; dos Santos, Leonardo A.; Fu, Guangwei; García Muñoz, Antonio; MacDonald, Ryan J.; Mikal-Evans, Thomas; Sanz-Forcada, Jorge; Wakeford, Hannah R. (2022)
    We present a uniform analysis of transit observations from the Hubble Space Telescope and Spitzer Space Telescope of two warm gas giants orbiting K-type stars-WASP-29b and WASP-80b. The transmission spectra, which span ...
  • An ultrahot gas-giant exoplanet with a stratosphere 
    Evans, Thomas M.; Sing, David K.; Kataria, Tiffany; Goyal, Jayesh; Nikolov, Nikolay; Wakeford, Hannah R.; Deming, Drake; Marley, Mark S.; Amundsen, David S.; Ballester, Gilda E.; Barstow, Joanna K.; Ben-Jaffel, Lotfi; Bourrier, Vincent; Buchhave, Lars A.; Cohen, Ofer; Ehrenreich, David; García Muñoz, Antonio; Henry, Gregory W.; Knutson, Heather; Lavvas, Panayotis; Etangs, Alain Lecavelier Des; Lewis, Nikole K.; López-Morales, Mercedes; Mandell, Avi M.; Sanz-Forcada, Jorge; Tremblin, Pascal; Lupu, Roxana (2017)
    Infrared radiation emitted from a planet contains information about the chemical composition and vertical temperature profile of its atmosphere. If upper layers are cooler than lower layers, molecular gases will produce ...
  • WASP-52b. The effect of star-spot correction on atmospheric retrievals 
    Bruno, Giovanni; Lewis, Nikole K.; Alam, Munazza K.; López-Morales, Mercedes; Barstow, Joanna K.; Wakeford, Hannah R.; Sing, David K.; Henry, Gregory W.; Ballester, Gilda E.; Bourrier, Vincent; Buchhave, Lars A.; Cohen, Ofer; Mikal-Evans, Thomas; García Muñoz, Antonio; Lavvas, Panayotis; Sanz-Forcada, Jorge (2020)
    We perform atmospheric retrievals on the full optical to infrared (0.3-5 µ m) transmission spectrum of the inflated hot Jupiter WASP-52b by combining HST/STIS, WFC3 IR, and Spitzer/IRAC observations. As WASP-52 is an active ...
