SUMMARY:What monsters lurk near planetary systems? - John Southworth (Keel

DESCRIPTION:Most stars occur in binary systems\, and this may have a cruci
 al effect on the intrinsic and observed properties of planets. Binarity ma
 y suppress planet formation\, modify the orbits of planets that do get dra
 gged into existence\, and confound our attempts to measure their physical 
 properties. I present a suite of high-resolution imaging studies of the ho
 st stars of transiting planets to demonstrate and explore these points. Co
 nversely\, stellar multiplicity may open new ways of understanding planeta
 ry systems. I present the discovery of a white dwarf and a low-mass eclips
 ing binary\, both bound to planetary systems discovered by the SuperWASP s
 urvey.\n
