- Аннотация: We use ALLWISE data release W1- and W2-band epoch photometry collected by the Wide-FieldInfrared Survey Explorer (WISE) to determine slopes of the period-luminosity relations for RR Lyraestars in 15 globular clusters in the corresponding bands. We further combine these results with V- andK-band photometry of Galactic field RR Lyrae stars to determine the metallicity slopes of the log P F -[Fe/H]-MK, log PF - [Fe/H]-MW1 , and log PF - [Fe/H]- MW2 period-metallicity-luminosity relations. Weinfer the zero points of these relations and determine the kinematical parameters of thick-disk and halo RR Lyraes via statistical parallax, and estimate the RR Lyrae-based distances to 18 Local-Group galaxies including the center of the Milky Way.
