The MACHO Project LMC Variable Star Inventory. VI. The Second Overtone Mode of Cepheid Pulsation From First/Second Overtone Beat Cepheids
Abstract
MACHO Project photometry of 45 LMC first and second overtone (FO and SO, respectively) beat Cepheids that pulsate in the FO and SO has been analyzed to determine the light-curve characteristics for the SO mode of Cepheid pulsation. We predict that singly periodic SO Cepheids will have nearly sinusoidal light curves; that we will only be able to discern SO Cepheids from fundamental (F) and FO Cepheids for P≲1.4 days; and that the SO distribution …
