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 Calar Alto's 3.5m telescope. Operating since 2016, it aims to find Earth-sized exoplanets around 2 (Earth masses) using Doppler spectroscopy (also called the radial velocity method). List of discovered minor planets Close to a hundred minor planets have been discovered at Calar Alto by astronomers Luboš Kohoutek, Kurt Birkle, Ulrich Hopp, Johann Baur, Krisztián Sárneczky, Gyula Szabó, Felix Hormuth and Hermann Boehnhardt. In addition, the Minor Planet Center, directly credits "Calar Alto" with the discovery of the following minor planets: Publications See also List of largest optical reflecting telescopes List of largest optical telescopes in the 20th century Cerro Tololo Inter-American Observatory La Silla Observatory List of minor planet discoverers Llano de Chajnantor Observatory Paranal Observatory Very Large Telescope References External links Calar Alto: Darkness In The Infrared ScienceDaily (Jan. 30, 2009) Carta de apoyo del Observatorio de Calar-Alto of April 2013 bird's eye view Astronomical observatories in Spain Buildings and structures in Andalusia Minor-planet discovering observatories
