TOI-908: a planet at the edge of the Neptune desert transiting a G-type star

Faith Hawthorn, Daniel Bayliss, David J. Armstrong +36

We present the discovery of an exoplanet transiting TOI-908 (TIC-350153977) using data from TESS sectors 1, 12, 13, 27, 28 and 39. TOI-908 is a T = 10.7 mag G-dwarf ( = 56…

Cold Jupiters and improved masses in 38 Kepler and K2 small planet systems from 3661 HARPS-N radial velocities. No excess of cold Jupiters in small planet systems

A. S. Bonomo, X. Dumusque, A. Massa +31

The exoplanet population characterized by relatively short orbital periods ( d) around solar-type stars is dominated by super-Earths and sub-Neptunes. However, these planets…

Two temperate Earth-mass planets orbiting the nearby star GJ1002

A. Suárez Mascareño, E. González-Álvarez, M. R. Zapatero Osorio +42

We report the discovery and characterisation of two Earth-mass planets orbiting in the habitable zone of the nearby M-dwarf GJ~1002 based on the analysis of the radial-velocity (RV…

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…
