Paper Abstract

The detection of Earth twins with the radial velocity (RV) method requires extreme Doppler precision and long term stability. One of the limiting factors in RV precision is the variation of the instrumental response due primarily to guiding errors, changes in focus or seeing. In order to provide extreme stability, we propose to use single-mode fibers to couple small amateur telescopes to a compact and ultra-stable high-resolution spectrograph. Here, we present a concept study for DREAMS, a Dedicated Robotic EArths-finding single-Mode Spectrograph, which should allow unprecedented RV precision on very bright stars.
