Mid-infrared Period–Luminosity Relations for Miras in the Large Magellanic Cloud

We present the mid-infrared (mid-IR) period–luminosity relations (PLRs) using over 1000 Mira variables in Large Magellanic Cloud, for four Wide-field Infrared Survey Explorer and Spitzer bands. These PLRs cover a mid-IR wavelength range from 3.4–22 ?m are presented separately oxygen-rich (O-rich) carbon-rich (C-rich) Miras. can be used to measure distances individual O-rich and/or C-rich stars with an accuracy of 5% 12%, respectively. They most accurate date.
