The fundamentals of Lyman-alpha exoplanet transits
James E. Owen, Ruth A. Murray-Clay, Ethan Schreyer +7
Lyman- transits have been detected from several nearby exoplanets and are one of our best insights into the atmospheric escape process. However, due to ISM absorption, we typica…
A unique hot Jupiter spectral sequence with evidence for compositional diversity
Megan Mansfield, Michael R. Line, Jacob L. Bean +11
The emergent spectra of close-in, giant exoplanets ("hot Jupiters") are expected to be distinct from those of self-luminous objects with similar effective temperatures because hot…
The Hubble PanCET program: Transit and Eclipse Spectroscopy of the Hot Jupiter WASP-74b
Guangwei Fu, Drake Deming, Erin May +12
Planets are like children with each one being unique and special. A better understanding of their collective properties requires a deeper understanding of each planet. Here we add…
The mass of Beta Pictoris c from Beta Pictoris b orbital motion
S. Lacour, J. J. Wang, L. Rodet +96
We aim to demonstrate that the presence and mass of an exoplanet can now be effectively derived from the astrometry of another exoplanet. We combined previous astrometry of Pic…
Detection of Ionized Calcium in the Atmosphere of the Ultra-Hot Jupiter WASP-76b
Emily K. Deibert, Ernst J. W. de Mooij, Ray Jayawardhana +9
Recent observations of the ultra-hot Jupiter WASP-76b have revealed a diversity of atmospheric species. Here we present new high-resolution transit spectroscopy of WASP-76b with GR…
The Impact of Mixing Treatments on Cloud Modelling in 3D Simulations of Hot Jupiters
D. A. Christie, N. J. Mayne, S. Lines +7
We present results of 3D hydrodynamical simulations of HD209458b including a coupled, radiatively-active cloud model ({\sc EddySed}). We investigate the role of the mixing by repla…
An inventory of atomic species in the atmosphere of WASP-121b using UVES high-resolution spectroscopy
Stephanie R. Merritt, Neale P. Gibson, Stevanus K. Nugroho +8
Ultra-hot Jupiters (UHJs) present excellent targets for atmospheric characterisation. Their hot dayside temperatures (T 2200 K) strongly suppress the formation of condens…
The Emission Spectrum of the Hot Jupiter WASP-79b from HST/WFC3
Trevor O. Foote, Nikole K. Lewis, Brian M. Kilpatrick +12
Here we present a thermal emission spectrum of WASP-79b, obtained via Hubble Space Telescope Wide Field Camera 3 G141 observations as part of the PanCET program. As we did not obse…
GRAVITY K-band spectroscopy of HD 206893 B: brown dwarf or exoplanet
J. Kammerer, S. Lacour, T. Stolker +94
We aim to reveal the nature of the reddest known substellar companion HD 206893 B by studying its near-infrared colors and spectral morphology and by investigating its orbital moti…
Ground-Based Transmission Spectroscopy with VLT FORS2: Evidence for faculae and clouds in the optical spectrum of the warm Saturn WASP-110b
Nikolay Nikolov, Gracjan Maciejewski, Savvas Constantinou +12
We present a ground-based optical transmission spectrum for the warm Saturn-mass exoplanet WASP-110b from two transit observations made with the FOcal Reducer and Spectrograph (FOR…
HST PanCET Program: A Complete Near-UV to Infrared Transmission Spectrum for the Hot Jupiter WASP-79b
Alexander D. Rathcke, Ryan J. MacDonald, Joanna K. Barstow +12
We present a new optical transmission spectrum of the hot Jupiter WASP-79b. We observed three transits with the STIS instrument mounted on HST, spanning 0.3 - 1.0 um. Combining the…
HST PanCET program: Non-detection of atmospheric escape in the warm Saturn-sized planet WASP-29 b
L. A. dos Santos, V. Bourrier, D. Ehrenreich +10
(Abridged) Short-period gas giant exoplanets are susceptible to intense atmospheric escape due to their large scale heights and strong high-energy irradiation. This process is thou…
The Hubble PanCET program: Long-term chromospheric evolution and flaring activity of the M dwarf host GJ 3470
V. Bourrier, L. A. dos Santos, J. Sanz-Forcada +9
Neptune-size exoplanets seem particularly sensitive to atmospheric evaporation, making it essential to characterize the stellar high-energy radiation that drives this mechanism. Th…
Gemini/GMOS Optical Transmission Spectroscopy of WASP-121b: signs of variability in an ultra-hot Jupiter?
Jamie Wilson, Neale P. Gibson, Joshua D. Lothringer +5
We present ground-based, spectroscopic observations of two transits of the ultra-hot Jupiter WASP-121b covering the wavelength range 500 - 950 nm using Gemini/GMOS. We use…
