J/AJ/136/2441   Metallicity of RR0 Lyrae in the galactic bulge   (Kunder+, 2008)

Metallicity analysis of MACHO Galactic bulge RR0 Lyrae stars from their light curves. Kunder A., Chaboyer B. <Astron. J., 136, 2441-2452 (2008)> =2008AJ....136.2441K
ADC_Keywords: Surveys ; Stars, variable ; Stars, population II ; Abundances Keywords: Galaxy: center - stars: abundances - stars: distances - stars: Population II - surveys Abstract: We present metallicities of 2690 RR0 Lyrae stars observed toward the MACHO Survey fields in the Galactic bulge. These [Fe/H] values are based upon an empirically-calibrated relationship that uses the Fourier coefficients of the light curve and are accurate to ±0.2dex. The majority of the RR0 Lyrae stars in our sample are located in the Galactic bulge, but 255 RR0 stars are associated with the Sagittarius (Sgr) dwarf galaxy. Description: The observations of the Galactic bulge were made by the MACHO team with a 1.27m telescope at Mount Stromlo Observatory (MSO), Australia. In total, seven seasons (1993-1999) of useful data were collected in the 94 Galactic bulge fields. File Summary:
