| Abstract: |
We have used the rate of change of pulsation period for the hot (DOV) pre-white dwarf PG1159-035 and the cool (DAV) white dwarf G117-B15A to measure their evolutionary time scales. We show that, for any multiperiodic star, we must take into account the effect of all pulsations simultaneously on the times of maximum of the pulsations to get reliable measurements of periods and phases. |
