论文摘要

这项工作是研究X射线/UV/光学恒星辐射对年轻高级二进制二进制二进制DQ TAU周围X射线/紫外线/光学恒星辐射的影响的一部分。由于天气恶劣而对2021年12月5日左右的ALMA观察结果被推迟了,但是支持Swift-Xrt-Uvot的支持太成功了。这些迅速的观察结果以及先前的X射线光学-MM数据表明,DQ Tau在Periastron附近保持强大的耀斑,为原始磁盘中气相离子化学作用的研究提供了独特的实验室。

This work is part of a multi-wavelength program to study the effects of X-ray/UV/optical stellar radiation on the chemistry of the circumbinary disk around the young high-eccentricity binary DQ Tau. ALMA observations for near/around December 5, 2021 periastron were postponed due to bad weather, but supporting Swift-XRT-UVOT TOO observations were successful. These Swift observations along with previous X-ray-optical-mm data show that DQ Tau keeps exhibiting powerful flares near periastron, offering a unique laboratory for studies of flare effects on the gas-phase ion chemistry in protoplanetary disks.
