TOI-4010: A System of Three Large Short-Period Planets With a Massive Long-Period Companion

Michelle Kunimoto, Andrew Vanderburg, Chelsea X. Huang +53

We report the confirmation of three exoplanets transiting TOI-4010 (TIC-352682207), a metal-rich K dwarf observed by TESS in Sectors 24, 25, 52, and 58. We confirm these planets wi…

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…

The CORALIE survey for southern extrasolar planets XIX. Brown dwarfs and stellar companions unveiled by radial velocity and astrometry

D. Barbato, D. Ségransan, S. Udry +17

A historical planet-search on a sample of 1647 nearby southern main sequence stars has been ongoing since 1998 with the CORALIE spectrograph at La Silla Observatory, with a backup…

TOI-1695 b: A Water World Orbiting an Early M Dwarf in the Planet Radius Valley

Collin Cherubim, Ryan Cloutier, David Charbonneau +38

Characterizing the bulk compositions of transiting exoplanets within the M dwarf radius valley offers a unique means to establish whether the radius valley emerges from an atmosphe…

A quarter century of spectroscopic monitoring of the nearby M dwarf Gl 514. A super-Earth on an eccentric orbit moving in and out of the habitable zone

M. Damasso, M. Perger, J. M. Almenara +31

We investigated the presence of planetary companions around the nearby (7.6 pc) and bright ( mag) early-type M dwarf Gl 514, analysing 540 radial velocities collected over nea…

Coralie radial-velocity search for companions around evolved stars (CASCADES) III. A new Jupiter host-star: in-depth analysis of HD 29399 using TESS data

C. Pezzotti, G. Ottoni, G. Buldgen +11

Context. Increasing the number of detected exoplanets is far from anecdotal, especially for long-period planets that require a long duration of observation. More detections imply a…
