论文摘要
我们介绍了强烈的中红外（miR）光的可检测性，这些光磁盘由M-dwarf恒星的明亮超级弹药照亮了微弱的碎屑盘。 M少量恒星周围周围的灰尘颗粒同时通过超叶片辐射加热。因此，人们可以期望它们在miR波长状态下的重新排放。 According to our model calculations for the Proxima Centauri system, the nearest M-dwarf star system, thermal emission echos from an inner ($r < 1~{\rm au}$) debris disk with a total mass down to that of the solar system's zodiacal dust are expected to emerge at wavelengths longer than $\sim 10~{\rm μm}$ with a strength comparable to or greater than白色的灯光。另外，可观察的echos来自内部 - （$ r \ lyssim 0.5〜 {\ rm au} $）碎屑盘被Energetic（$ \ gtrsim 10^{33.5}〜{\ rm ergs} $）辐射（$ \ gtrsim 10^{33.5}〜{\ rm ergs} $）我们的仿真结果表明，使用高速光学仪器（例如绿洲）及其使用地面mir仪器（例如Tao/mimizuku）的迅速随访的超弹药监测，可以检测到太阳能邻域耀斑恒星周围的碎屑磁盘的这些mir灯回波。
We present the detectability of strong mid-infrared (MIR) light echoes from faint debris disks illuminated by bright superflares of M-dwarf stars. Circumstellar dust grains around an M-dwarf star are simultaneously heated by superflare radiation. One can thus expect their re-emission in the MIR wavelength regime. According to our model calculations for the Proxima Centauri system, the nearest M-dwarf star system, thermal emission echos from an inner ($r < 1~{\rm au}$) debris disk with a total mass down to that of the solar system's zodiacal dust are expected to emerge at wavelengths longer than $\sim 10~{\rm μm}$ with a strength comparable to or greater than a white-light superflare. Also, observable echos from inner- ($r \lesssim 0.5~{\rm au}$) debris disks irradiated by energetic ($\gtrsim 10^{33.5}~{\rm ergs}$) superflares of nearby ($D < 3~{\rm pc}$) M-dwarfs are expected. Our simulation results indicate that superflare monitoring using high-speed optical instruments like OASES and its prompt follow-up using ground-based MIR instruments, such as TAO/MIMIZUKU, can detect these MIR light echoes from debris disks around solar neighborhood flare stars.
