A planetary system with a sub-Neptune planet in the habitable zone of TOI-2093

J. Sanz-Forcada, E. González-Álvarez, M. R. Zapatero Osorio +33

Aims. We aim to confirm and measure the mass of the transiting planet candidate around the K5V star TOI-2093, previously announced by the Transiting Exoplanet Survey Satellite (TES…

The CARMENES search for exoplanets around M dwarfs. Revisiting the GJ 317, GJ 463, and GJ 3512 systems and two newly discovered planets orbiting GJ 9773 and GJ 508.2

J. C. Morales, I. Ribas, S. Reffert +33

Surveys for exoplanets indicate that the occurrence rate of gas giant planets orbiting late-type stars in orbits with periods shorter than 1000 days is lower than in the case of Su…

The CARMENES search for exoplanets around M dwarfs. A sub-Neptunian mass planet in the habitable zone of HN Lib

E. González-Álvarez, J. Kemmer, P. Chaturvedi +29

We report the discovery of HN Lib b, a sub-Neptunian mass planet orbiting the nearby ( = 6.25 pc) M4.0 V star HN Lib detected by our CARMENES radial-velocity (RV) survey…

A super-Earth and a mini-Neptune near the 2:1 MMR straddling the radius valley around the nearby mid-M dwarf TOI-2096

F. J. Pozuelos, M. Timmermans, B. V. Rackham +72

Several planetary formation models have been proposed to explain the observed abundance and variety of compositions of super-Earths and mini-Neptunes. In this context, multitransit…

The CARMENES search for exoplanets around M dwarfs. Guaranteed time observations Data Release 1 (2016-2020)

I. Ribas, A. Reiners, M. Zechmeister +102

The CARMENES instrument was conceived to deliver high-accuracy radial velocity (RV) measurements with long-term stability to search for temperate rocky planets around a sample of n…

TOI-1468: A system of two transiting planets, a super-Earth and a mini-Neptune, on opposite sides of the radius valley

P. Chaturvedi, P. Bluhm, E. Nagel +67

We report the discovery and characterization of two small transiting planets orbiting the bright M3.0V star TOI-1468 (LSPM J0106+1913), whose transit signals were detected in the p…

A multi-planetary system orbiting the early-M dwarf TOI-1238

E. González-Álvarez, M. R. Zapatero Osorio, J. Sanz-Forcada +53

Two transiting planet candidates with super-Earth radii around the nearby K7--M0 dwarf star TOI-1238 were announced by TESS. We aim to validate their planetary nature using precise…

Two planets around Kapteyn's star : a cold and a temperate super-Earth orbiting the nearest halo red-dwarf

Guillem Anglada-Escudé, Pamela Arriagada, Mikko Tuomi +21

Exoplanets of a few Earth masses can be now detected around nearby low-mass stars using Doppler spectroscopy. In this paper, we investigate the radial velocity variations of Kaptey…
