SUMMARY:How do hot Jupiters migrate? - Andrew Collier Cameron (University 
 of St Andrews)

DESCRIPTION:In the five years since the first large-scale transit surveys 
 began operating\, over 100 gas-giant planets have been discovered in close
  orbits around their host stars. A sizeable minority among these so-called
  hot Jupiters are found to be in orbits that are strongly inclined or even
  retrograde with regard to the spin axes of their host stars. This surpris
 ing result suggests that migration in a protoplanetary disc may not be the
  only way to bring a Jupiter into a very close orbit. In this talk I will 
 review the properties of the ensemble of transiting hot Jupiters\, and exa
 mine the empirical evidence for the various planet-migration processes tha
 t may shape these systems.
