The CARMENES consortium built two high-resolution spectrographs for the visual (VIS) and near-infrared (NIR) wavelength ranges that are in operation at Calar Alto's 3.6m telescope since Jan 2016. CARMENES opened the view to detailed M dwarf spectroscopy and is carrying out a program to search for planets around 300 low-mass stars. After obtaining more than 19,000 spectra, results include the discovery of numerous nearby Super-Earths, including two in the habitable zone around one of the lowest mass stars, the study of planetary atmospheres, stellar magnetism and activity, and fundamental work on low-mass star parameters and high-resolution methodologies.
