AI 中文总结
研究 CQ Tau 恒星邻域结构，通过假设存在周期 10 年的伴星进行尘埃和气体相互作用模拟，发现 M 类恒星虽能形成类似密度降低区域，但尘埃环位置与观测不符，而大质量行星在特定轨道可能形成符合观测的环形尘埃结构。
AI 中文摘要
有间接迹象表明 CQ Tau 恒星附近存在伴星。在亮度变化中发现了 10 年的周期。圆盘图像显示有一个约 25 天文单位大小的广泛空洞，周围是一个尘埃环，分布最大值在 53 天文单位附近。假设存在一颗周期为 10 年的伴星，对具有 CQ Tau 参数的恒星附近的尘埃和气体相互作用进行了模拟。结果表明，一颗处于高度拉长轨道的 M 类恒星能够在系统质心周围形成一个密度降低的区域，其大小与观测到的相近。然而，这种情况下的尘埃环结构比观测到的明显更靠近恒星。已获得证据表明，一颗处于外部相对双星轨道的大质量行星，可能在与观测到的距离相似处形成环形尘埃结构。
英文摘要
There are indirect signs of the presence of a companion near the star CQ\,Tau. A period of 10\;years was found in the brightness changes. The image of the disk shows an extensive cavity with a size of about 25~AU, surrounded by a dust ring with a distribution maximum near 53~AU. A simulation of the interaction of dust and gas in the vicinity of the star with the CQ\,Tau parameters was carried out, assuming the existence of a companion in an orbit with a period of 10\;years. It was shown that an M-class star in a highly elongated orbit is capable of forming a region of reduced density around the center of mass of the system, with a size close to the observed one. However, the dust ring-like structure in this case is located noticeably closer to the star than observed. Evidence has been obtained that a massive planet in an outer, relatively binary orbit, could form a ring-shaped dust structure at a distance similar to that observed.
