Michel Bonnardeau, Franz-Josef Hambsch
TL;DR
This paper presents photometric observations of the RR Lyrae star AR Serpentis, revealing two Blazhko modulations with periods of 89 and 108 days, including evidence of irregularities in the modulations.
Contribution
The study provides detailed observational data and analysis of the Blazhko effect in AR Serpentis, highlighting the presence of two modulations with irregularities.
Findings
Detection of two Blazhko modulations with periods 89 and 108 days
Evidence of irregularities in the modulation patterns
Enhanced understanding of Blazhko phenomena in RR Lyrae stars
Abstract
Photometric observations in 2010-2014 of the RR Lyrae star AR Serpentis are presented and analyzed. Two Blazhko modulations of comparable amplitude are detected, with the periods 89 and 108 days, and with evidence for irregularities.
