Strömgren uvbyB photoelectric photometry of the variable star AT And ispresented. Analysis of this data corroborates the periods compiled by Kholopov(1985). Strömgren photometry has been used for the determination of reddeningand the physical parameters log g and log Te, as well as the metallicity [...

| Resumo: | Strömgren uvbyB photoelectric photometry of the variable star AT And ispresented. Analysis of this data corroborates the periods compiled by Kholopov(1985). Strömgren photometry has been used for the determination of reddeningand the physical parameters log g and log Te, as well as the metallicity [Fe/H]. Thedetermination of MV is discussed assuming AT And is an RR Lyrae star. |
