论文摘要
外太阳系中冰冷体之间的红色和色彩多样性是了解太阳系状态和历史的重要线索之一。但是，颜色分布的起源仍然值得商bat。在这里，我们证明了在实验室实验中仅在低温温度下才能稳定的红色色素。在85 k处用含氮的冷冻质量照射的甲醇和含水冰的含红色的颜色。与众所周知的耐火有机硫蛋白相比，冰的加热时，冰上褪色并消失在120-150 k时，红色的颜色在120-150 k处消失，甚至在室温加热至室温时也是稳定的。在低温条件下，红色着色的温度依赖性可以为没有超红色的色彩在外部太阳系中更接近太阳提供新的可能解释。我们的结果意味着，针对低温环境的红色材料可用于研究外部太阳系的色彩多样性和形成机理。
Reddish coloration and color diversity among icy bodies in the outer solar system are one of the significant clues for understanding the status and history of the solar system. However, the origin of color distribution remains debatable. Here, we demonstrate reddish coloration that is stable only at cryogenic temperatures in a laboratory experiment. The reddish coloration was produced on methanol- and water-containing ice irradiated with nitrogen-containing cryoplasma at 85 K. The reddish color visually faded and disappeared at 120-150 K as the ice was heated, unlike well-known refractory organic tholins that are stable even when heated to room temperature. This temperature dependence of reddish coloration under cryogenic conditions could provide a new possible explanation for the absence of ultra-red coloration closer to the Sun in the outer solar system. Our result implies that a reddish material specific to cryogenic environments is useful for the investigation of color diversity and formation mechanism of the outer solar system.
