Constraints on Metastable Helium in the Atmospheres of WASP-69b and WASP-52b with Ultra-Narrowband Photometry
Shreyas Vissapragada, Heather A. Knutson, Nemanja Jovanovic +7
Infrared observations of metastable 2S helium absorption with ground- and space-based spectroscopy are rapidly maturing, as this species is a unique probe of exoplanet atmosphe…
The Orbit of WASP-12b is Decaying
Samuel W. Yee, Joshua N. Winn, Heather A. Knutson +6
WASP-12b is a transiting hot Jupiter on a 1.09-day orbit around a late-F star. Since the planet's discovery in 2008, the time interval between transits has been decreasing by $29\p…
Exploring Whether Super-Puffs Can Be Explained as Ringed Exoplanets
Anthony L. Piro, Shreyas Vissapragada
An intriguing, growing class of planets are the "super-puffs," objects with exceptionally large radii for their masses and thus correspondingly low densities ($\lesssim0.3\rm\,g\,c…
Diffuser-Assisted Infrared Transit Photometry for Four Dynamically Interacting \textit{Kepler} Systems
Shreyas Vissapragada, Daniel Jontof-Hutter, Avi Shporer +11
We present ground-based infrared transit observations for four dynamically interacting \textit{Kepler} planets, including Kepler-29b, Kepler-36c, KOI-1783.01, and Kepler-177c, obta…
On the Energetics of the HCO + C CH + CO Reaction and Some Astrochemical Implications
Daniel W. Savin, Roshan G. Bhaskar, Shreyas Vissapragada +1
We explore the energetics of the titular reaction, which current astrochemical databases consider open at typical dense molecular (i.e., dark) cloud conditions. As is common for re…
