Ultra-Low Amplitude Variables in the Large Magellanic Cloud-Classical Cepheids, Pop. II Cepheids, RV Tau Stars, and Binary Variables

Buchler, Robert; Wood, Peter R; Soszynski, Igor

Description

A search for variable stars with ultra-low amplitudes (ULAs), in the millimagnitude range, has been made in the combined MACHO and OGLE databases in the broad vicinity of the Cepheid instability strip in the HR diagram. A total of 25 singly periodic and 4 multiply periodic ULA objects have been uncovered. Our analysis does not allow us to distinguish between pulsational and ellipsoidal (binary) variabilities, nor between Large Magellanic Cloud (LMC) and foreground objects. However, the objects...[Show more]
