Planets around evolved intermediate-mass stars III. Planet candidates and long-term activity signals in six open clusters
E. Delgado Mena, J. Gomes da Silva, J. P. Faria +6
[abridged]The aim of this work is to search for planets around evolved stars, with a special focus on stars more massive than 2\,M in light of previous findings that show a…
TESS and CHEOPS Discover Two Warm Sub-Neptunes Transiting the Bright K-dwarf HD 15906
Amy Tuson, Didier Queloz, Hugh P. Osborn +119
We report the discovery of two warm sub-Neptunes transiting the bright (G = 9.5 mag) K-dwarf HD 15906 (TOI 461, TIC 4646810). This star was observed by the Transiting Exoplanet Sur…
Optical and near-infrared stellar activity characterization of the early M dwarf Gl~205 with SOPHIE and SPIRou
P. Cortes-Zuleta, I. Boisse, B. Klein +41
The stellar activity of M dwarfs is the main limitation for discovering and characterizing exoplanets orbiting them since it induces quasi-periodic RV variations. We aim to charact…
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…
TOI-1452 b: SPIRou and TESS reveal a super-Earth in a temperate orbit transiting an M4 dwarf
Charles Cadieux, René Doyon, Mykhaylo Plotnykov +53
Exploring the properties of exoplanets near or inside the radius valley provides insights on the transition from the rocky super-Earths to the larger, hydrogen-rich atmosphere mini…
The HARPS search for southern extra-solar planets XXXV. The interesting case of HD41248: stellar activity, no planets?
N. C. Santos, A. Mortier, J. P. Faria +21
The search for planets orbiting metal-poor stars is of uttermost importance for our understanding of the planet formation models. However, no dedicated searches have been conducted…
