英文摘要	In this work, we propose a novel scenario to probe the interactions between dark matter (DM) particles and electrons via hydrogen-atmosphere pulsating white dwarfs (DAVs) in globular clusters. In this special configuration, the DM particles, which are predominantly captured by multiple scattering with the electrons in a DAV, would annihilate by pairs and provide extra energy source to the DAV. This mechanism slows down the natural cooling evolution which can be presented by the period variation rates of pulsation modes. The differences between the secular rates predicted by the precise asteroseismology and the secular rates obtained from observation can reveal the DM-electron interactions. An important observable has been proposed and corresponding estimations have been made. According to the estimations, if this scenario could be implemented in the near future, the potential sensitivity on m(chi) (DM particle's mass) and sigma(chi,e) (elastic scattering cross section between DM and electron) could be hopefully extended to a region 5 GeV less than or similar to m(chi) less than or similar to 10(4) GeV and sigma(chi,e) greater than or similar to 10(-40) cm(2). Combining with indirect DM detection results, this could give us a cross check on the existence of such leptonphilic DM particles to some extent.
