ExoGemS The Effect of Offsets from True Orbital Parameters on Exoplanet High-Resolution Transmission Spectra
Yasmine J. Meziani, Laura Flagg, Jake D. Turner +4
High-resolution spectroscopy (HRS) plays a crucial role in characterizing exoplanet atmospheres, revealing detailed information about their chemical composition, temperatures, and…
A Time-Resolved High-Resolution Spectroscopic Analysis of Ionized Calcium and Dynamical Processes in the Ultra-Hot Jupiter HAT-P-70 b
Adam B. Langeveld, Emily K. Deibert, Mitchell E. Young +5
We present the first transmission spectroscopy study of an exoplanet atmosphere with the high-resolution mode of the new Gemini High-resolution Optical SpecTrograph (GHOST) instrum…
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…
Is TiO emission present in the ultra-hot Jupiter WASP-33b? A reassessment using the improved ExoMol Toto line list
Dilovan B. Serindag, Stevanus K. Nugroho, Paul Mollière +3
[abridged] Efficient absorption of stellar UV and visible radiation by TiO and VO is predicted to drive temperature inversions in the upper atmospheres of hot Jupiters. However, fe…
Arid or Cloudy: Characterizing the Atmosphere of the super-Earth 55 Cancri e using High-Resolution Spectroscopy
Abhinav Jindal, Ernst J. W. de Mooij, Ray Jayawardhana +6
The nearby super-Earth 55 Cnc e orbits a bright (V = 5.95 mag) star with a period of ~ 18 hours and a mass of ~ 8 Earth masses. Its atmosphere may be water-rich and have a large sc…
Search for TiO and Optical Night-side Emission from the Exoplanet WASP-33b
Miranda K. Herman, Ernst J. W. de Mooij, Ray Jayawardhana +1
With a temperature akin to an M-dwarf, WASP-33b is among the hottest Jupiters known, making it an ideal target for high-resolution optical spectroscopy. By analyzing both transmiss…
Detection of Fe I in the atmosphere of the ultra-hot Jupiter WASP-121b, and a new likelihood-based approach for Doppler-resolved spectroscopy
Neale P. Gibson, Stephanie Merritt, Stevanus K. Nugroho +10
High-resolution Doppler-resolved spectroscopy has opened up a new window into the atmospheres of both transiting and non-transiting exoplanets. Here, we present VLT/UVES observatio…
ESA Voyage 2050 White Paper: Detecting life outside our solar system with a large high-contrast-imaging mission
Ignas Snellen, Simon Albrecht, Guillem Anglada-Escude +64
In this white paper, we recommend the European Space Agency plays a proactive role in developing a global collaborative effort to construct a large high-contrast imaging space tele…
Storms or Systematics? The changing secondary eclipse depth of WASP-12b
Matthew J. Hooton, Ernst J. W. de Mooij, Christopher A. Watson +4
WASP-12b is one of the most well-studied transiting exoplanets, as its highly-inflated radius and its 1.1 day orbit around a G0-type star make it an excellent target for atmospheri…
Revisiting the potassium feature of WASP-31b at high-resolution
Neale P. Gibson, Ernst J. W. de Mooij, Thomas M. Evans +4
The analysis and interpretation of exoplanet spectra from time-series observations remains a significant challenge to our current understanding of exoplanet atmospheres, due to the…
Characterising exo-ringsystems around fast-rotating stars using the Rossiter-McLaughlin effect
E. J. W. de Mooij, C. A. Watson, M. A. Kenworthy
Planetary rings produce a distinct shape distortion in transit lightcurves. However, to accurately model such lightcurves the observations need to cover the entire transit, especia…
The Changing Face of Centauri B: Probing plage and stellar activity in K-dwarfs
A. P. G. Thompson, C. A. Watson, E. J. W. de Mooij +1
A detailed knowledge of stellar activity is crucial for understanding stellar dynamos, as well as pushing exoplanet radial-velocity detection limits towards Earth analogue confirma…
