DESCRIPTION:White Dwarf Suns: Can Dead Stars Support Life in the Current 
 and Future Universe? The majority of stars in our Galaxy\, and in other 
 galaxies throughout the Universe\, will eventually evolve into white dwa
 rfs. This notably includes our own Sun. The effects that this process wi
 ll have on the Solar System at large are of intrinsic interest to its in
 habitants\, since the consequences of the Sun's post-main sequence evolu
 tion will determine the Solar System's future contents and suitability f
 or supporting life. Due to the presence of accreted photospheric metals 
 and/or infrared excesses indicative of circumstellar dust disks\, some w
 hite dwarfs are already known to harbor the remnants of a planetary syst
 em. Recently\, this has been bolstered by the first detection of a dwarf
  planet-sized object transiting a white dwarf. Thus\, if planetary syste
 ms can survive the post-main sequence evolution of their parent star\, t
 hen white dwarfs will also become the most common hosts for planets in t
 he future and\, by extension\, potential sites for the continuing existe
 nce of life as the Universe ages. I will review the effects on a planeta
 ry system of its host star's evolution into a white dwarf\, and discuss 
 the implications for providing conditions around the remnant white dwarf
  that can nominally support life (e.g.\, a planetary body with liquid wa
 ter)\, resulting from both luminous and non-luminous energy flux.
