Session 59 - Pulsating/Variable Stars.
Display session, Wednesday, June 12
Great Hall,
We present the results of linear non-adiabatic pulsation models for intermediate-mass stars with metallicities typical of Milky Way, LMC, and SMC objects. A total of 1560 models of Milky Way Cepheids and 1470 models of LMC and SMC Cepheids have been analysed for mode excitation and pulsation period. We compare our results with the observed period ratios seen in 12 Milky Way Beat Cepheids and the 45 LMC Beat Cepheids discovered by the MACHO project. The probable range of period ratios for SMC Beat Cepheids is also discussed.
