TOI-1801 b: A temperate mini-Neptune around a young M0.5 dwarf

M. Mallorquín, E. Goffo, E. Pallé +79

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, and the a…

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…

Gaussian processes for radial velocity modeling Better rotation periods and planetary parameters with the quasi-periodic kernel and constrained priors

Stephan Stock, Jonas Kemmer, Diana Kossakowski +3

In this study we present an analysis of the performance and properties of the quasi-periodic (QP) GP kernel, which is the multiplication of the squared-exponential kernel by the ex…

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…

The CARMENES search for exoplanets around M dwarfs, Wolf 1069 b: Earth-mass planet in the habitable zone of a nearby, very low-mass star

D. Kossakowski, M. Kürster, T. Trifonov +47

We present the discovery of an Earth-mass planet () on a 15.6d orbit of a relatively nearby (9.6pc) and low-mass () M…

The CARMENES search for exoplanets around M dwarfs: Stable radial-velocity variations at the rotation period of AD~Leonis -- A test case study of current limitations to treating stellar activity

D. Kossakowski, M. Kürster, Th. Henning +34

Context: A challenge with radial-velocity (RV) data is disentangling the origin of signals either due to a planetary companion or to stellar activity. In fact, the existence of a p…
