CARMENES: Blue Planets Orbiting Red Dwarfs

摘要

CARMENES (Calar Alto high-Resolution search for M dwarfs with Exo-earths with Near-infrared and optical Echelle Spectrographs) will conduct a radial-velocity survey of ~ 300 M dwarfs with the 3.5 m telescope at the Calar Alto Observatory. The CARMENES instrument is currently under construction; it consists of two independent échelle spectrographs, which together cover the wavelength range 0.55 - 1.7 μm at a spectral resolution of R = 82,000. The spectrographs and the fiber input are designed with a goal of 1 m/s radial velocity precision using simultaneous calibration with emission-line lamps.
