Revisiting the multi-planetary system of the nearby star HD 20794: Confirmation of a low-mass planet in the habitable zone of a nearby G-dwarf
N. Nari, X. Dumusque, N. C. Hara +44
Close-by Earth analogs and super-Earths are of primary importance because they will be preferential targets for the next generation of direct imaging instruments. Bright and close-…
Radial-velocity discovery of a second planet in the TOI-1338/BEBOP-1 circumbinary system
Matthew R. Standing, Lalitha Sairam, David V. Martin +24
We report the detection of a gas-giant planet in orbit around both stars of an eclipsing binary star system that also contains the smaller, inner transiting planet TOI-1338b. The n…
Detection of barium in the atmospheres of the ultra-hot gas giants WASP-76b and WASP-121b
T. Azevedo Silva, O. D. S. Demangeon, N. C. Santos +33
High-resolution spectroscopy studies of ultra-hot Jupiters have been key in our understanding of exoplanet atmospheres. Observing into the atmospheres of these giant planets allows…
Espresso observations of HE 01075240 and other CEMP-no stars with
D. Aguado, P. Molaro, E. Caffau +22
HE 01075240 is a hyper metal-poor star with . We performed high-res observations with the ESPRESSO spectrograph at the VLT to constrain the kinematical propert…
Stellar activity correction using PCA decomposition of shells
M. Cretignier, X. Dumusque, F. Pepe
Context. Stellar activity and instrumental signals are the main limitations to the detection of Earth-like planets using the radial velocity (RV) technique. Recent studies show tha…
A candidate short-period sub-Earth orbiting Proxima Centauri
J. P. Faria, A. Suárez Mascareño, P. Figueira +34
Proxima Centauri is the closest star to the Sun. This small, low-mass, mid M dwarf is known to host an Earth-mass exoplanet with an orbital period of 11.2 days within the habitable…
