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 […]

GCM Constraints On The Detectability Of The CO2-CH4 Biosignature Pair On TRAPPIST-1e With JWST
Terrestrial exoplanets such as TRAPPIST-1e will be observed in a new capacity with JWST/NIRSpec, which is expected to be able to detect CO2, CH4, and O2 signals, if present, with […]

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.
