Short period, massive planets, known as hot Jupiters (HJs), have been discovered around ∼ 1 percent of local field stars. The inward migration necessary to produce HJs may be ‘low eccentricity’, due to torques in the primordial disc, or ‘high eccentricity’ (HEM). The latter involves exciting high orbital eccentricity, allowing sufficiently close passages with the host star to raise circularising tides in the planet. We present an analytic framework for quantifying the role of dynamical encounters…
