p-winds: an open-source Python code to model planetary outflows and upper atmospheres
Leonardo A. Dos Santos, Aline A. Vidotto, Shreyas Vissapragada +6
Atmospheric escape is considered to be one of the main channels for evolution in sub-Jovian planets, particularly in their early lives. While there are several hypotheses proposed…
Titanium oxide and chemical inhomogeneity in the atmosphere of the exoplanet WASP-189b
Bibiana Prinoth, H. Jens Hoeijmakers, Daniel Kitzmann +21
The temperature of an atmosphere decreases with increasing altitude, unless a shortwave absorber exists that causes a temperature inversion. Ozone plays this role in the Earth`s at…
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…
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…
HD22496b: the first ESPRESSO standalone planet discovery
J. Lillo-Box, J. P. Faria, A. Suárez Mascareño +32
The ESPRESSO spectrograph is a new powerful tool to detect and characterize extrasolar planets. Its design allows unprecedented radial velocity precision (down to a few tens of cm/…
Characterizing exoplanetary atmospheres at high resolution with SPIRou: Detection of water on HD 189733 b
Anne Boucher, Antoine Darveau-Bernier, Stefan Pelletier +29
We present the first exoplanet atmosphere detection made as part of the SPIRou Legacy Survey, a Large Observing Program of 300 nights exploiting the capabilities of SPIRou, the new…
Warm terrestrial planet with half the mass of Venus transiting a nearby star
Olivier D. S. Demangeon, M. R. Zapatero Osorio, Y. Alibert +42
The advent of a new generation of radial velocity instruments has allowed us to break the one Earth-mass barrier. We report a new milestone in this context with the detection of th…
Where is the Water? Jupiter-like C/H ratio but strong HO depletion found on Boötis b using SPIRou
Stefan Pelletier, Björn Benneke, Antoine Darveau-Bernier +18
The present-day envelope of gaseous planets is a relic of how these giant planets originated and evolved. Measuring their elemental composition therefore presents a powerful opport…
A sub-Neptune and a non-transiting Neptune-mass companion unveiled by ESPRESSO around the bright late-F dwarf HD 5278 (TOI-130)
A. Sozzetti, M. Damasso, A. S. Bonomo +45
[Abridged] We exploit the extreme radial velocity (RV) precision of the ultra-stable echelle spectrograph ESPRESSO on the VLT to unveil the physical properties of the transiting su…
Six transiting planets and a chain of Laplace resonances in TOI-178
A. Leleu, Y. Alibert, N. C. Hara +152
Determining the architecture of multi-planetary systems is one of the cornerstones of understanding planet formation and evolution. Resonant systems are especially important as the…
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…
Large Interferometer For Exoplanets (LIFE): I. Improved exoplanet detection yield estimates for a large mid-infrared space-interferometer mission
S. P. Quanz, M. Ottiger, E. Fontanet +68
One of the long-term goals of exoplanet science is the atmospheric characterization of dozens of small exoplanets in order to understand their diversity and search for habitable wo…
