Detection of a high-velocity sodium feature on the ultra-hot Jupiter WASP-121 b
J. V. Seidel, F. Borsa, L. Pino +19
Ultra-hot Jupiters, with their high equilibrium temperatures and resolved spectral lines, have emerged as a perfect testbed for new analysis techniques in the study of exoplanet at…
HD 23472: A multi-planetary system with three super-Earths and two potential super-Mercuries
S. C. C. Barros, O. D. S. Demangeon, Y. Alibert +7
We report the characterisation of a multi-planetary system composed of five exoplanets orbiting the K-dwarf HD~23472 (TOI-174). In addition to the two super-Earths that were previo…
Detailed stellar activity analysis and modelling of GJ 832: Reassessment of the putative habitable zone planet GJ 832c
P. Gorrini, N. Astudillo-Defru, S. Dreizler +27
Context. Gliese 832 (GJ 832) is an M2V star hosting a massive planet on a decade-long orbit, GJ 832b, discovered by radial velocity (RV). Later, a super Earth or mini-Neptune orbit…
Transit timing variations of AU Microscopii b and c
Gy. M. Szabó, Z. Garai, A. Brandeker +76
Here we report large-amplitude transit timing variations (TTVs) for AU\,Microcopii b and c as detected in combined TESS (2018, 2020) and CHEOPS (2020, 2021) transit observations. A…
PASTIS: Bayesian extrasolar planet validation II. Constraining exoplanet blend scenarios using spectroscopic diagnoses
A. Santerne, R. F. Díaz, J. -M. Almenara +7
The statistical validation of transiting exoplanets proved to be an efficient technique to secure the nature of small exoplanet signals which cannot be established by purely spectr…
Chemical abundances and kinematics of 257 G-, K-type field giants. Setting a base for further analysis of giant-planet properties orbiting evolved stars
V. Zh. Adibekyan, L. Benamati, N. C. Santos +9
We performed a uniform and detailed abundance analysis of 12 refractory elements (Na, Mg, Al, Si, Ca, Ti, Cr, Ni, Co, Sc, Mn, and V) for a sample of 257 G- and K-type evolved stars…
