Metallicity of Galactic RR Lyrae from Optical and Infrared Light Curves. II....
We present new period-ϕ 31-[Fe/H] relations for first-overtone RRL stars (RRc), calibrated over a broad range of metallicities (-2.5 ≲ [Fe/H] ≲ 0.0) using the...

Machine-learned Identification of RR Lyrae Stars from Sparse, Multi-band Data: The PS1 Sample
RR Lyrae stars may be the best practical tracers of Galactic halo (sub-)structure and kinematics. The PanSTARRSl (PSI) Зтг survey offers multi-band,...
