摘要: We present and discuss an extensive data set for the non-Blazhko ab-type RR Lyrae star SDSS J015450+001501, including optical Sloan Digital Sky Survey ugriz light curves spectroscopic data, LINEAR Catalina Sky Survey unfiltered curves, infrared Two Micron All (2MASS) JHK_s Wide-field Infrared Explorer W1 W2 curves. Most notable is that obtained by 2MASS include close to 9000 photometric measures collected over 3.3 yr provide exceedingly precise view of near-infrared variability. These demonstrate static atmosphere models are insufficient explain multiband photometric light-curve behavior strong constraints nonlinear pulsation stars. It a challenge modelers produce theoretical can presented here, which we make publicly available.
