Invited_talk abstract details

Hot subdwarfs are stars that have survived the core helium flash and are now in (or recently finished with) the core helium burning stage. At the hot end of the Horizontal Branch, many of these stars are multiperiodic pulsators. These pulsations have revealed details of their global and internal structure. While many features of their structure deduced from seismic fits have confirmed what we expected from evolutionary considerations, there have been some surprises as well. In this talk, I'll review past progress, current issues, and speculate on what the future holds for the asteroseismic study of these stars.
