Search for extra-solar planets with high precision radial velocity curves

摘要

This Ph.D. Thesis has as general subject the study of extrasolar planets using the radial velocity technique from both, instrumental and observative, points of view. Two main parts compose the work: the upgrade of the spectrograph FOCES, a high resolution spectrograph that will be installed next year at the Wendelstein Observatory, and theudsearch of giant planets around stars in the open cluster Messier-67 (M67).
