We present an analytic description of tides raised on a star by a smallorbiting body. In particular, we highlight the disproportionate effect ofeccentricity and thus the scope for using these tides to detect andcharacterise the orbits of exoplanets and brown dwarfs. The tidal distortionsof the star produced by an eccentric orbit are, in comparison to a circularorbit, much richer in detail, and potentially visible from any viewing angle.The magnitude of these variations is much larger than that in a circular orbitof the same semi-major axis. These variations are visible in both photometricand spectroscopic data, and dominate other regular sources of phase variability(e.g reflection and Doppler beaming) over a particularly interesting portion ofparameter space. These tidal signatures will be a useful tool for planetdetection on their own, and used in concert with other methods provide powerfulconstraints on planetary and stellar properties.
