Simultaneous photometric and CARMENES spectroscopic monitoring of fast-rotating M dwarf GJ 3270. Discovery of a post-flare corotating feature

E. N. Johnson, S. Czesla, B. Fuhrmeister +33

Context: Active M dwarfs frequently exhibit large flares, which can pose an existential threat to the habitability of any planet in orbit in addition to making said planets more di…

Precise mass and radius of a transiting super-Earth planet orbiting the M dwarf TOI-1235: a planet in the radius gap?

P. Bluhm, R. Luque, N. Espinoza +78

We report the confirmation of a transiting planet around the bright, inactive M0.5 V star TOI-1235 (TYC 4384-1735-1, V = 11.5 mag), whose transit signal was detected in the photome…

CARMENES input catalogue of M dwarfs: III. Rotation and activity from high-resolution spectroscopic observations

S. V. Jeffers, P. Schoefer, A. Lamert +18

CARMENES is a spectrograph for radial velocity surveys of M dwarfs with the aim of detecting Earth-mass planets orbiting in the habitable zones of their host stars. To ensure an op…

TOI-1201 b: A mini-Neptune transiting a bright and moderately young M dwarf

D. Kossakowski, J. Kemmer, P. Bluhm +62

We present the discovery of a transiting mini-Neptune around TOI-1201, a relatively bright and moderately young early M dwarf ( 9.5 mag, 600-800 Myr) in an equal-m…

The CARMENES search for exoplanets around M dwarfs - Photospheric parameters of target stars from high-resolution spectroscopy

V. M. Passegger, A. Reiners, S. V. Jeffers +14

The new CARMENES instrument comprises two high-resolution and high-stability spectrographs that are used to search for habitable planets around M dwarfs in the visible and near-inf…

An ultra-short-period transiting super-Earth orbiting the M3 dwarf TOI-1685

P. Bluhm, E. Palle, K. Molaverdikhani +51

Dynamical histories of planetary systems, as well as atmospheric evolution of highly irradiated planets, can be studied by characterizing the ultra-short-period planet population,…
