SUMMARY:A Song of Ice and Fire: the Fate of Planetary Systems After Stella
 r Death - Andrew Vanderburg (Wisconsin-Madison)

DESCRIPTION:\nIn the past 30 years\, astronomers have discovered thousands
  of planets orbiting stars outside the solar system. Most of the exoplanet
 s we know of today orbit stars that will eventually exhaust their nuclear 
 fuel\, expand into red giants\, shed their outer layers\, and contract int
 o dense remnants called white dwarfs. How does the process of stellar deat
 h affect any orbiting planets in the system? I will review our knowledge o
 f planets beyond the main sequence and discuss new insights gleaned from o
 ur discoveries of two very different systems: a disintegrating minor plane
 t around WD 1145+017 and an intact giant planet candidate around WD 1856+5
 34. I will conclude by discussing the prospects for habitability in white 
 dwarf systems long after the host star's death and how with some luck\, we
  may be able to test these ideas in the next decade.\n
