New Suspected Variable (NSV) Stars in the Galactic Open Cluster NGC 2264. Periodic Variables: A CoRoT View

Abstract

A recent release of CoRoT mission exoplanet fields' data included those for stars likely connected with the Galactic open cluster NGC 2264 that are also included in the New Suspected Variables' Catalogue, NSV (Kukarkin et al. 1982), and its Supplement (Kazarovets et al. 1998). Using the VizieR B/COROT version these data were crossmatched with the VizieR version of the NSV at B/GCVS to two arcseconds. Of the approximately seventy objects from the cluster and its surroundings so matched, the strictly and cleanly periodic objects with sufficient cycles for analysis from the relatively short duration CoRoT SRa01 (Short Run [Galactic] Anticentre 01) dataset, and which were also mostly unambiguous as to variability type, were analysed.
