J/AcA/59/137 ASAS Galactic fundamental mode RR Lyrae stars (Szczygiel+, 2009)
Galactic fundamental mode RR Lyrae stars. Period-amplitude diagram, metallicities and distribution. Szczygiel D.M., Pojmanski G., Pilecki B. <Acta Astron., 59, 137-167 (2009)> =2009AcA....59..137S
ADC_Keywords: Stars, variable ; Photometry ; Abundances, [Fe/H] Keywords: stars: Population II - stars: variables: RR Lyr - stars: abundances - stars: fundamental parameters Abstract: We have analyzed 1455 fundamental mode RR Lyr stars of the Galactic field, using the All Sky Automated Survey (ASAS) data. The sample covers 75% of the sky and contains objects in the close neighborhood of the Sun, within 4kpc distance. Unlike in the previous analysis of the close field RRab stars, we see a clear manifestation of the Oosterhoff groups on the period-amplitude diagram. The relation for Oosterhoff I type variables becomes strongly flattened at large V amplitudes, which was not observed for globular cluster RR Lyr. Description: The V-band light curves of all 1455 RRab stars in ACVS were extracted from the catalog and only points with quality flags 'A' and 'B' were retained. File Summary:
