DESCRIPTION:Speakers: Jia-Shu Niu (Shanxi University)\nIn our galaxy\, the
  white dwarfs (WDs) will inevitably capture the dark matter (DM) particles
  streaming through them\, if there exist interactions between DM particles
  and nuclei/electrons. At the same time\, these DM particles can also be e
 vaporated by the nuclei/electrons in a WD if they have proper mass and the
  WD is not too cold. The evaporation of DM particles will lead to a faster
  cooling evolution than that predicted by the stellar evolution theory.\nI
 n this work\, we ascribe the faster cooling evolution of three observed WD
 s to the capture and evaporation of DM particles\, and get the possible re
 gions of DM particle’s mass and DM-electron cross section.\nThe results 
 are beyond the detection capabilities of current direct detection experime
 nts and shouldbe cross checked by more novel scenarios in the future.\n\nh
