Kawaler, S. D. ; Winget, D. E. ; Hansen, C. J. Abstract The splitting of high order nonradial g-modes due to slow rotation in models of hot prewhite dwarf stars of 0.60 solar mass are calculated. The effects of rotational spin-up, produced by gravitational contraction, on the rate of evolutionary period change for the cases of uniform and differential rotation are investigated. For models in the luminosity range of PG 1159 - 035 (L of about 100 solar luminosities), it is found that rotation rates of a few thousand seconds for modes with m less than about -2 produce values of d(ln P)/dt that are consistent with the measurement of the rate of period change of the 516-second period of PG 1159 - 035.
