SUMMARY:White Dwarfs in Binary Stars - Tom Marsh (Warwick)
DTSTART:20141023T153000Z

UID:TALK55146@talks.cam.ac.uk
CONTACT:Simon Hodgkin
DESCRIPTION:Over the past ten years we have started to discover large numb
 ers of white dwarfs in binaries with low mass stars or other white dwarfs.
  I\nwill show how these systems are starting to provide us with observatio
 nal tests of how white dwarfs build up mass through accretion\, a long-sta
 nding stumbling block for "single degenerate" models of Type Ia supernovae
 . I will show how the same observations can test the structure models that
  underlie all white dwarf research\, including their future use in mapping
  the star formation history of the Milky way. Finally\, I will discuss evi
 dence for planetary debris around white dwarfs\, and planets around white 
 dwarf binaries.
