Paper Abstract

New techniques for the high precision measurement of variations in stellar radial velocities now allow a precision of better than 5 m/s to be obtained in routine telescopic observations. Some of the factors limiting velocity precision and how they can be overcome are discussed. Also presented are applications of these new techniques to the problems of detection of planetary systems around other stars and the use of stellar oscillations to determine interior properties of the stars.
