论文摘要
我们使用大型麦哲伦云中的1000多个Mira变量（LMC），为四个广阔的红外红外调查Explorer（Wise）和四个Spitzer频段介绍了使用1000多个Mira变量的中红外（MID-IR）$ - $ luminosity关系（PLR）。这些PLR涵盖了MID-IR波长范围从$ 3.4 $ $ $ M到$ 22 $ $ $ M $ M，并分别用于富含氧气（O-RICH）和富含碳富含碳（富含碳）的Miras。这些关系可用于测量单个O-RICH和/或C-RICH MIRA恒星的距离，其精度分别为$ 5 \％$和$ 12 \％$。它们是迄今为止IR中最准确的Mira PLR。
We present the mid-infrared (mid-IR) period$-$luminosity relations (PLRs) using over 1000 Mira variables in the Large Magellanic Cloud (LMC), for the four Wide-Field Infrared Survey Explorer (WISE) and the four Spitzer bands. These PLRs cover a mid-IR wavelength range from $3.4$ $μ$m to $22$ $μ$m and are presented separately for the oxygen-rich (O-rich) and carbon-rich (C-rich) Miras. These relations can be used to measure distances to individual O-rich and/or C-rich Mira stars with the accuracy of $5\%$ and $12\%$, respectively. They are the most accurate Mira PLRs in the mid-IR to date.
