The light curves of the short-period variable stars in ω Centauri.

PORETTI E.

Abstract (from CDS):

The Fourier decomposition was applied to the light curves of the short period variable stars discovered by the OGLE team (Kaluzny et al. 1996A&AS..120..139K, 1997A&AS..122..471K) in ω Cen. The progression of the φ21 parameter as a function of the period is extended toward very short periods as the new values connected directly to those of stars located in the Galaxy. However, two groups of stars deviate: the first is located around 0.038d and it shows rather high φ21 values; the second is the origin of a small change in the slope around 0.050d. The reality of the two features is discussed. The peculiarity of the light curve of OGLEGC 26 is also emphasized.
