Detecting the proposed CH4-CO2 biosignature pair with the James Webb Space Telescope: TRAPPIST-1e and the effect of cloud/haze
Thomas Mikal-Evans
It is widely anticipated that the James Webb Space Telescope (JWST) will be transformative for exoplanet studies. It has even been suggested that JWST could provide the first oppor…
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…
Transmission spectroscopy with VLT FORS2: a featureless spectrum for the low-density transiting exoplanet WASP-88b
Petros Spyratos, Nikolay Nikolov, John Southworth +10
We present ground-based optical transmission spectroscopy of the low-density hot Jupiter WASP-88b covering the wavelength range 4413-8333 Å with the FORS2 spectrograph on the Very…
Possibilities for an Aerial Biosphere in Temperate Sub Neptune-Sized Exoplanet Atmospheres
Sara Seager, Janusz J. Petkowski, Maximilian N. Günther +3
The search for signs of life through the detection of exoplanet atmosphere biosignature gases is gaining momentum. Yet, only a handful of rocky exoplanet atmospheres are suitable f…
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: 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 TESS Objects of Interest Catalog from the TESS Prime Mission
Natalia M. Guerrero, S. Seager, Chelsea X. Huang +102
We present 2,241 exoplanet candidates identified with data from the Transiting Exoplanet Survey Satellite (TESS) during its two-year prime mission. We list these candidates in the…
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…
Masses and compositions of three small planets orbiting the nearby M dwarf L231-32 (TOI-270) and the M dwarf radius valley
Vincent Van Eylen, N. Astudillo-Defru, X. Bonfils +69
We report on precise Doppler measurements of L231-32 (TOI-270), a nearby M dwarf ( pc, M, R), which hosts three transiting p…
