New Pulsating Variable Stars and Eclipsing Binaries in NGC 6871.

ZHOU A.-Y.

Abstract (from CDS):

Leveraging publicly available Transiting Exoplanet Survey Satellite data, I conducted a small regional survey centered on the δ Scuti star V1821 Cyg in the open cluster NGC 6871, spanning a radius of 1°. This survey yielded a remarkable 1530 newly classified variable stars, encompassing: 198 eclipsing binary systems, 12 of which exhibit pulsating or rotating components, 105 γ Doradus stars, 116 δ Scuti stars, 526 rotating variable stars, and dozens of other types. It is not surprising that no RR Lyrae stars were found in this particular young open cluster.
