外星黄道尘

艺术家想像下的行星，靠近著围绕着中心的恒星，显示出灿烂的外行星黄道光延伸至天空，淹没了银河的光辉。

外星黄道尘是填充在系外行星系统面上，大小在1至100微米的无定形碳和硅酸盐尘埃颗粒。它是系外行星类比于太阳系中观察到的黄道尘，特别是在小行星主带内观察到大小在1至100微米的颗粒。相较于黄道尘，这些颗粒可能来自于彗星的释气，或是更大的天体，像是小行星之间的碰撞。外星黄道尘云的成分往往是被检测到过多红外线发射主序星周围的岩屑盘。通常，外星黄道尘是指这些岩屑盘在距离恒星几个天文单位之内，温度最高和最内侧的部分。这些外星黄道尘的形状可以显示系外行星在动力学上的影响，和指出行星的存在^[1]。因为它通常位于一颗恒星的适居带附近，外星黄道尘可能是企图捕捉类地行星影像时重要的噪音来源。
