Combined analysis of the 12.8 and 15 JWST/MIRI eclipse observations of TRAPPIST-1 b

Elsa Ducrot, Pierre-Olivier Lagage, Michiel Min +36

The first JWST/MIRI photometric observations of TRAPPIST-1 b allowed for the detection of the thermal emission of the planet at 15 , suggesting that the planet could be a bare…

Characterization of seven transiting systems including four warm Jupiters from SOPHIE and TESS

N. Heidari, G. H'ebrard, E. Martioli +65

We present the study of seven systems, three of which TOI-2295, TOI-2537, and TOI-5110 are newly discovered planetary systems. Through the analysis of TESS photometry, SOPHIE radia…

An impact-free mechanism to deliver water to terrestrial planets and exoplanets

Quentin Kral, Paul Huet, Camille Bergez-Casalou +3

To date, the most widespread scenario is that the Earth originated without water and was brought to the planet mainly due to impacts by wet asteroids coming from further out in spa…

Gl 725A b: a potential super-Earth detected with SOPHIE and SPIRou in an M dwarf binary system at 3.5 pc

P. Cortes-Zuleta, I. Boisse, M. Ould-Elhkim +34

We report the discovery of a super-Earth candidate orbiting the nearby mid M dwarf Gl\,725A using the radial velocity (RV) method. The planetary signal has been independently ident…

The COBREX archival survey: improved constraints on the occurrence rate of wide-orbit substellar companions. I. A uniform re-analysis of 400 stars from the GPIES survey

V. Squicciarini, J. Mazoyer, A. -M. Lagrange +4

Direct imaging (DI) campaigns are uniquely suited to probing the outer regions around young stars and looking for giant exoplanet and brown dwarf companions, hence providing key co…
