| Abstract: |
The search for extrasolar planets relies strongly on indirect methods. The most successful of these, the radial velocity method, is particularly vulnerable to contamination by stellar phenomena. In this short review I discuss the different physical phenomena behind the radial-velocity signals stemming from the star, and how they might be misinterpreted as originating in a planetary companion or preclude its detection. I also present some techniques proposed for minimizing their impact and conclude by stating their importance in the context of very high-precision radial-velocity instruments and their scientific goals. |
