Context. The CARMENES exoplanet survey of M dwarfs has obtained more than 18 000
spectra of 329 nearby M dwarfs over the past five years as part of its guaranteed time …

Context. The CARMENES instrument, installed at the 3.5 m telescope of the Calar Alto
Observatory in Almería, Spain, was conceived to deliver high-accuracy radial velocity (RV) …

Exploring the properties of exoplanets near or inside the radius valley provides insight on
the transition from the rocky super-Earths to the larger, hydrogen-rich atmosphere mini …

We investigate and compare the composition of M-dwarf planets in systems with only one
known planet (" singles") to those residing in multiplanet systems (" multis") and the …

We report the discovery, mass, and radius determination of TOI-1801 b, a temperate mini-
Neptune around a young M dwarf. TOI-1801 b was observed in TESS sectors 22 and 49 …

Context. The NASA mission TESS is currently doing an all-sky survey from space to detect
transiting planets around bright stars. As part of the validation process, the most promising …

The number of exoplanets discovered already exceeds 5000 and continues to increase
daily. The characterization of exoplanets will be the main goal of future space missions. The …

One of the main objectives of the Transiting Exoplanet Survey Satellite (TESS) mission is the
discovery of small rocky planets around relatively bright nearby stars. Here, we report the …

The Kepler and TESS missions have demonstrated that planets are ubiquitous. However,
the success of these missions heavily depends on ground-based radial velocity (RV) …

We present the discovery of a new Jovian-sized planet, TOI-3757 b, the lowest-density
transiting planet known to orbit an M dwarf (M0V). This planet was discovered around a …
