On the incidence rate of first overtone Blazhko stars in the Large Magellanic Cloud. (2006)

Keywords : stars variables: RR Lyrae - stars: fundamental parameters - galaxies: Magellanic Clouds

Abstract:By using the full span of multicolor data on a representative sample of first overtone RR Lyrae stars in the Large Magellanic Cloud (LMC), we revisit the problem of the incidence rate of the amplitude/phase-modulated (Blazhko) stars. Methods. Multicolor data, obtained by the MAssive Compact Halo Objects (MACHO) project, are utilized through a periodogram averaging method.
