SUMMARY:Rogue Waves on Pulsating White Dwarf Stars - JJ Hermes (U of North 
 Carolina)
DESCRIPTION:Rogue Waves on Pulsating White Dwarf Stars - JJ Hermes (U of N
 orth Carolina) 
\n 
\nWhile it has been an efficient planet-discovery ma
 chine\, the unblinking photometry of the Kepler space telescope has also r
 evolutionized the way we look at pulsating stars. I will discuss some of t
 he rapid advances Kepler has enabled in our understanding of white dwarf s
 tars\, including a completely unexpected new physical phenomenon: large-am
 plitude outbursts in the coolest pulsating white dwarfs. These outbursts a
 re essentially rogue waves\, sporadically increases the overall stellar br
 ightness by up to 15%. The outbursts have provided fresh insight into how 
 pulsation energy can be transferred through nonlinear resonances\, as well
  as the eventual cessation of pulsations in cool white dwarfs.
