Correctly taking into account the effects of rotation on the oscillation frequencies of stars presents one of the major challenges in the analysis of asteroseismic data. We have modified Christensen-Dalsgaard's adipack adiabatic pulsations package to include the effects of rotation in a second-order perturbative approach. The code calculates stellar oscillations, accounting for the effect of the star's rotation to first order in the eigenfunctions and to second order in the eigenfrequencies. We present our initial results for zero-age main-sequence (ZAMS), main-sequence and near-main-sequence models, including a model of a 1.98M{sub}⊙, 0.686 Gyr-old star that may be representative of the δ-Scuti star BU Cnc.
