Transmission Spectroscopy of WASP-79b from 0.6 to 5.0 m

Kristin S. Sotzen, Kevin B. Stevenson, David K. Sing +18

As part of the PanCET program, we have conducted a spectroscopic study of WASP-79b, an inflated hot Jupiter orbiting an F-type star in Eridanus with a period of 3.66 days. Building…

Detection of Na, K and HO in the hazy atmosphere of WASP-6b

Aarynn L. Carter, Nikolay Nikolov, David K. Sing +13

We present new observations of the transmission spectrum of the hot Jupiter WASP-6b both from the ground with the Very Large Telescope (VLT) FOcal Reducer and Spectrograph (FORS2)…

WASP-52b. The effect of starspot correction on atmospheric retrievals

Giovanni Bruno, Nikole K. Lewis, Munazza K. Alam +13

We perform atmospheric retrievals on the full optical to infrared () transmission spectrum of the inflated hot Jupiter WASP-52b by combining HST/STIS, WFC3 IR…

The Hubble PanCET program: An extensive search for metallic ions in the exosphere of GJ 436 b

L. A. dos Santos, D. Ehrenreich, V. Bourrier +15

(Abridged) The quiet M2.5 star GJ 436 hosts a warm Neptune that displays an extended atmosphere that dwarfs its own host star. Predictions of atmospheric escape in such planets sta…

The HST PanCET Program: Exospheric Mg II and Fe II in the Near-UV transmission spectrum of WASP-121b using Jitter Decorrelation

David K. Sing, Panayotis Lavvas, Gilda E. Ballester +17

We present HST near-ultraviolet (NUV) transits of the hot Jupiter WASP-121b, acquired as part of the PanCET program. Time series spectra during two transit events were used to meas…

Photochemical hazes in sub-Neptunian atmospheres with focus on GJ 1214 b

Panayotis Lavvas, Tommi Koskinen, Maria Steinrueck +2

We study the properties of photochemical hazes in super-Earths/mini-Neptunes atmospheres with particular focus on GJ1214b. We evaluate photochemical haze properties at different me…
