Doppler Tomography as a tool for characterising exoplanet atmospheres II: an analysis of HD 179949 b

S. M. Matthews, C. A. Watson, E. J. W. de Mooij +5

High-resolution Doppler spectroscopy provides an avenue to study the atmosphere of both transiting and non-transiting planets. This powerful method has also yielded some of the mos…

High-resolution atmospheric retrievals of WASP-121b transmission spectroscopy with ESPRESSO: Consistent relative abundance constraints across multiple epochs and instruments

Cathal Maguire, Neale P. Gibson, Stevanus K. Nugroho +4

Recent progress in high-resolution transmission spectroscopy has offered new avenues in which to characterise the atmospheres of transiting exoplanets. High-resolution cross-correl…

A quantitative assessment of the VO line list: Inaccuracies hamper high-resolution VO detections in exoplanet atmospheres

S. de Regt, A. Y. Kesseli, I. A. G. Snellen +2

Metal hydrides and oxides are important species in hot-Jupiters since they can affect their energy budgets and the thermal structure of their atmospheres. One such species is VO, w…

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…

Detection of Fe\,{\sc i} Emission in the Day-side Spectrum of WASP-33b

Stevanus K. Nugroho, Neale P. Gibson, Ernst J. W. de Mooij +4

We analyze the high-resolution emission spectrum of WASP-33b taken using the High Dispersion Spectrograph (R\,\,165,000) on the 8.2-m Subaru telescope. The data cover \…

Searching for Thermal Inversion Agents in the Transmission Spectrum of MASCARA-2b/KELT-20b: Detection of Neutral Iron and Ionised Calcium HK Lines

Stevanus K. Nugroho, Neale P. Gibson, Ernst J. W. de Mooij +3

We analyse the transmission spectra of KELT-20b/MASCARA-2b to search for possible thermal inversion agents. The data consist of three transits obtained using HARPSN and one using C…

Non-detection of TiO and VO in the atmosphere of WASP-121b using high-resolution spectroscopy

Stephanie R. Merritt, Neale P. Gibson, Stevanus K. Nugroho +9

Thermal inversions have long been predicted to exist in the atmospheres of ultra-hot Jupiters. However, detection of two species thought to be responsible -- TiO and VO -- remain e…

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…

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…
