High-resolution detection of neutral oxygen and non-LTE effects in the atmosphere of KELT-9b
Francesco Borsa, Luca Fossati, Tommi Koskinen +2
Oxygen is a constituent of many of the most abundant molecules detected in exoplanetary atmospheres and a key ingredient for tracking how and where a planet formed. In particular,…
The Rossiter-McLaughlin effect Revolutions: An ultra-short period planet and a warm mini-Neptune on perpendicular orbits
V. Bourrier, C. Lovis, M. Cretignier +34
Comparisons of the alignment of exoplanets with a common host star can be used to distinguish among concurrent evolution scenarios. However, multi-planet systems usually host mini-…
Retrieving the transmission spectrum of HD 209458b using CHOCOLATE: A new chromatic Doppler tomography technique
E. Esparza-Borges, M. Oshagh, N. Casasayas-Barris +29
Multiband photometric transit observations or low-resolution spectroscopy (spectro-photometry) are normally used to retrieve the broadband transmission spectra of transiting exopla…
Into the Storm: Diving into the winds of the ultra hot Jupiter WASP-76 b with HARPS and ESPRESSO
J. V. Seidel, D. Ehrenreich, A. Allart +26
Despite swift progress in the characterisation of exoplanet atmospheres in composition and structure, the study of atmospheric dynamics has not progressed at the same speed. While…
The GAPS Programme with HARPS-N at TNG. XXXI. The WASP-33 system revisited with HARPS-N
F. Borsa, A. F. Lanza, I. Raspantini +33
[abridged] We analyse four transits of WASP-33b observed with the optical high-resolution HARPS-N spectrograph to confirm its nodal precession, study its atmosphere and investigate…
The obliquity and atmosphere of the ultra-hot Jupiter TOI-1431b (MASCARA-5b): A misaligned orbit and no signs of atomic ormolecular absorptions
M. Stangret, E. Pallé, N. Casasayas-Barris +21
Ultra-hot Jupiters are defined as giant planets with equilibrium temperatures larger than 2000 K. Most of them are found orbiting bright A-F type stars, making them extremely suita…
Five carbon- and nitrogen-bearing species in a hot giant planet's atmosphere
Paolo Giacobbe, Matteo Brogi, Siddharth Gandhi +40
The atmospheres of gaseous giant exoplanets orbiting close to their parent stars (hot Jupiters) have been probed for nearly two decades. They allow us to investigate the chemical a…
Constraints on the mass and atmospheric composition and evolution of the low-density young planet DS Tuc A b
S. Benatti, M. Damasso, F. Borsa +9
We performed a radial velocity (RV) monitoring of the 40 Myr old star DS Tuc A with HARPS at the ESO-3.6m to determine the planetary mass of its 8.14-days planet, first revealed by…
The atmosphere of HD 209458b seen with ESPRESSO. No detectable planetary absorptions at high resolution
N. Casasayas-Barris, E. Palle, M. Stangret +37
We observed two transits of the iconic gas giant HD 209458b between 380 and 780 nm, using the high-resolution ESPRESSO spectrograph. The derived planetary transmission spectrum exh…
The GAPS Programme at TNG. XXIX. No detection of reflected light from 51 Peg b using optical high-resolution spectroscopy
G. Scandariato, F. Borsa, D. Sicilia +44
The analysis of exoplanetary atmospheres by means of high-resolution spectroscopy is an expanding research field which provides information on chemical composition, thermal structu…
