The CARMENES Search For Exoplanets Around M Dwarfs. Guaranteed Time Observations Data Release 1 (2016-2020)
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 nearby cool stars.

A Long-period Planet Around GJ 1151 Measured With CARMENES And HARPS-N Data
Detecting a planetary companion in a short-period orbit through radio emission from the interaction with its host star is a new prospect in exoplanet science.

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
We present the discovery of an Earth-mass planet (Mbsini=1.36±0.21M⊕) on a 15.6d orbit of a relatively nearby (d∼9.6pc) and low-mass (0.167±0.011M⊙) M5.0V star, Wolf 1069.

Two Temperate Earth-mass Planets Orbiting The Nearby Star GJ1002
We report the discovery and characterisation of two Earth-mass planets orbiting in the habitable zone of the nearby M-dwarf GJ~1002 based on the analysis of the radial-velocity (RV) time series […]

The CARMENES Search For Exoplanets Around M Dwarfs. Variability On Long Timescales As Seen In Chromospheric Indicators
It is clearly established that the Sun has an 11-year cycle that is caused by its internal magnetic field. This cycle is also observed in a sample of M dwarfs.
