TOI-7510: A solar-analog system of three transiting giant planets near a Laplace resonance chain
J. M. Almenara, A. Leleu, T. Guillot +23
We report the confirmation and initial characterization of a compact and dynamically rich multiple giant planet system orbiting the solar analog TOI-7510. The system was recently i…
A Decade of Transit-Timing Measurements Confirm Resonance in the K2-19 System
Paige M. Entrican, Erik A. Petigura, Antoine C. Petit +2
K2-19 is a star, slightly smaller than the Sun, that hosts three transiting planets. Two of these, K2-19 b and c, are between the size of Neptune and Saturn and have orbital period…
Characterizing planetary systems with SPIRou: Detection of a sub-Neptune in a 6-day period orbit around the M dwarf Gl 410
A. Carmona, X. Delfosse, M. Ould-Elhkim +42
The search for exoplanets around nearby M dwarfs represents a crucial milestone in the census of planetary systems in the vicinity of our Solar System. Since 2018 our team is carry…
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…
