On the membership of variable stars in Galactic globular clusters: the Oosterhoff gap.

PRUDIL Z. and ARELLANO FERRO A.

Abstract (from CDS):

We have performed a critical evaluation of the membership status of all variable stars in globular clusters recorded in the Catalogue of Variable Stars in Globular Clusters (CVSGC) curated by Christine Clement. To this end, we employed the systematic and bulky membership analysis performed by E. Vasiliev and H. Baumgardt based on the proper motions and parallaxes given in Gaia-EDR3. We found numerous variables in the CVSGC which are in fact field stars, which is particularly the case for globular clusters located in the Galactic bulge. Using the newly acquired list of reliable cluster members we examine the Oosterhoff dichotomy present among the Milky Way (MW) globular clusters using their RR Lyrae stars content. We confirm the presence of the Oosterhoff gap, separating both Oosterhoff groups. The Oosterhoff gap is mostly populated by globular clusters associated with MW dwarf galaxies and globular clusters with a low number of fundamental mode RR Lyrae variables. Several of the clusters in the Oosterhoff gap were previously linked to past merger events (e.g. Kraken/Heracles).
