TL;DR
High-precision space photometry from CoRoT and Kepler has revealed complex, multifaceted behaviors in RR Lyrae stars, including irregular Blazhko effects, low-amplitude frequencies, and phenomena like period doubling, challenging previous simplistic models.
Contribution
This paper summarizes new observational insights into RR Lyrae stars obtained from space telescopes, highlighting their complex pulsation behaviors and the need to revise existing models.
Findings
Detection of irregular and cycle-to-cycle changes in the Blazhko effect.
Identification of low-amplitude frequencies and phenomena like period doubling.
Evidence that RR Lyrae stars are more complex than previously thought.
Abstract
RR Lyrae stars for a long time had the reputation of being rather simple pulsators, but the advent of high-precision space photometry has meanwhile changed this picture dramatically. This article summarizes the results obtained for two remarkable Blazhko RR Lyrae stars and discusses how our view of RR Lyrae stars has changed since the availability of ultra-precise satellite photometry as it is obtained by CoRoT and Kepler. Both stars, CoRoT 105288363 and V445 Lyrae, show a multitude of phenomena that were impossible to observe from the ground, either because of the small amplitude of the effect, or because uninterrupted long-term monitoring was required for a detection. Not only was it found that strong and irregular cycle-to-cycle changes of the Blazhko effect can occur, and that seemingly chaotic phenomena need to be accounted for when modeling the Blazhko effect, but also a rich…
