uvby-β Photometry of the RR Lyrae Star AC And. (2005). Revista Mexicana De Astronomía Y Astrofísica, 41(2), 461-470. https://astronomia.unam.mx/journals/rmxaa/article/view/2005rmxaa..41..461p
Abstract
Strömgren uvby-β and differential V photoelectric photometry of the variable star AC And is presented. Analysis of this data, as well as data from the literature, corroborates the periods proposed by Fitch & Szeidl (1976). Strömgren photometry has been used for the determination of the reddening and the physical parameters log g and log Te, as well as the metallicity [Fe/H]. The determination of Mv is also discussed and, in view of the results, we propose that AC And is an RR Lyrae star with possible anomalous chemical composition.Similar Articles
