The Complete transmission spectrum of WASP-39b with a precise water constraint
Hannah R. Wakeford, David K. Sing, Drake Deming +12
WASP-39b is a hot Saturn-mass exoplanet with a predicted clear atmosphere based on observations in the optical and infrared. Here we complete the transmission spectrum of the atmos…
Hubble PanCET: An isothermal day-side atmosphere for the bloated gas-giant HAT-P-32Ab
N. Nikolov, D. K. Sing, J. Goyal +20
We present a thermal emission spectrum of the bloated hot Jupiter HAT-P-32Ab from a single eclipse observation made in spatial scan mode with the Wide Field Camera 3 (WFC3) aboard…
A library of ATMO forward model transmission spectra for hot Jupiter exoplanets
Jayesh M. Goyal, Nathan Mayne, David K. Sing +11
We present a grid of forward model transmission spectra, adopting an isothermal temperature-pressure profile, alongside corresponding equilibrium chemical abundances for 117 observ…
The Very Low Albedo of WASP-12b From Spectral Eclipse Observations with
Taylor J. Bell, Nikolay Nikolov, Nicolas B. Cowan +11
We present an optical eclipse observation of the hot Jupiter WASP-12b using the Space Telescope Imaging Spectrograph on board the Hubble Space Telescope. These spectra allow us to…
An ultrahot gas-giant exoplanet with a stratosphere
Thomas M. Evans, David K. Sing, Tiffany Kataria +24
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 low…
HAT-P-26b: A Neptune-Mass Exoplanet with a Well Constrained Heavy Element Abundance
Hannah R. Wakeford, David K. Sing, Tiffany Kataria +11
A correlation between giant-planet mass and atmospheric heavy elemental abundance was first noted in the past century from observations of planets in our own Solar System, and has…
