SUMMARY:Measuring Black Hole Spin - Ramesh Narayan\, Harvard
DTSTART:20101125T163000Z

CONTACT:scott chapman
DESCRIPTION:An astrophysical black hole is completely described with just 
 two parameters: its mass and its dimensionless spin. A few dozen black hol
 es have mass estimates\, but until recently none had a reliable spin estim
 ate. In the last few years\, our group has measured spin parameters for a 
 small number of black holes in X-ray binaries. The talk will describe the 
 method we use to make these measurements and will discuss implications of 
 the results obtained so far.
