Free Astronomy Magazine January-February 2019

JANUARY-FEBRUARY 2019 research team undertook, from 2016 to 2017, a monitoring campaign with the spectrometer CARMENES (Calar Alto high- Resolution search for M dwarfs with Ex- oearths with Near-infrared and optical Échelle Spectrographs) at the Observatorio de Calar Alto (Almería, Spain), collecting ra- dial velocity measurements so precise as to detect differences of 1 m/s. These data have been integrated with equally accurate data gathered with other high-resolution spec- trographs, such as ESO’s HARPS and UVES, in Chile, and Telescopio Nazionale Galileo’s HARPS-N, in the Canary Islands.
