Blazhko Effect in Double Mode Cepheids
P. Moskalik, Z. Kolaczkowski
TL;DR
This paper investigates the Blazhko effect, a periodic modulation of amplitude and phase, in double mode Cepheids using data from OGLE and MACHO surveys, revealing a new pulsational behavior.
Contribution
It provides the first detailed analysis of the Blazhko effect in double mode Cepheids, expanding understanding of their pulsational variability.
Findings
Detection of periodic amplitude and phase modulation in double mode Cepheids
Identification of the Blazhko effect as a new pulsational phenomenon in these stars
Analysis based on a combined OGLE and MACHO dataset
Abstract
Systematic survey for multiperiodicity in the LMC Cepheids (Moskalik, Kolaczkowski & Mizerski 2004, 2006) has led to discovery of several new forms of pulsational behaviour. One of them is periodic amplitude and phase modulation observed in many first/second overtone (FO/SO) double mode Cepheids. In the current paper we present detailed discussion of this newly discovered phenomenon, based on a combined OGLE+MACHO sample of double mode pulsators.
