Activity{Related Radial Velocity Variation in Cool Stars
Planets have been detected orbiting several solar-type stars using high-precision radial velocity (v r) measurements. While changes in v r can be measured with an accuracy of a few m s ?1 , there has been relatively little study of how other astrophysical processes, such as magnetic activity, may eeect the observed velocities. In this paper, we use published data and simple models to explore th...
