Improving Earth-like planets' detection with an ELT: the differential radial velocity experiment
2007
Astronomy and Astrophysics
Context. Direct detection of Earth-like planets around a nearby star is extremely difficult for ground-based telescopes equipped with the eXtreme Adaptative Optics system. Aims. We propose to combine high-precision radial velocity with an ELT to detect extrasolar planets with a feasible coronagraph. Methods. In this context, we investigated the detectability of Earth-like extrasolar planets with an ELT of 42 m equipped with the spectro-coronagraphic instrument in an eXtrem Adaptive Optics
