CARMENES survey

Exoplanet survey

The CARMENES survey (Calar Alto high-Resolution search for M-dwarfs with Exoearths with Near-infrared and optical Échelle Spectrographs) is a project to examine approximately 300 M-dwarf stars for signs of exoplanets with the CARMENES instrument on the Spanish Calar Alto's 3.5m telescope.[1]

Operating since 2016, it aims to find Earth-sized exoplanets around 2 ME (Earth masses) using Doppler spectroscopy (also called the radial velocity method).[2] More than 20 exoplanets have been found through CARMENES, among them Teegarden b, considered one of the most potentially habitable exoplanets.[3][4] Another potentially habitable planet found is Gliese 357 d.[5]
