RR Lyrae stars with Blazhko modulations in the OGLE collection
Karolina Bakowska, Radoslaw Smolec
TL;DR
This paper reports on the detection of multiple Blazhko modulations in RR Lyrae stars from the OGLE Galactic bulge collection, highlighting complex modulation behaviors in these variable stars.
Contribution
It presents the first identification of multiple Blazhko modulations in individual RR Lyrae stars within the OGLE dataset.
Findings
Detection of two Blazhko periods in one star
Identification of three Blazhko modulations in another star
Highlights complexity of Blazhko phenomena in RR Lyrae stars
Abstract
We briefly discuss three cases of RR~Lyrae variable stars with Blazhko modulation from the OGLE Galactic bulge collection. In one of the discussed stars modulation with two periods is detected, in other star, we detect three Blazhko modulations.
