这篇文章结合了对年轻联星系统中单个组成星及其相关盘的光谱研究的相对全面的回顾,概述了进行更深入研究的必要性,并预览了对100颗年轻联星的高光谱和高角分辨率调查的结果主要位于金牛座和蛇夫座星星形成区域。观测到的光谱,合成光谱分析,和3个系统的初步结果,说明功率和潜力的自适应光学馈,高分辨率,红外光谱,我们的年轻的双星和他们的拱星盘和环境的动力学和物理特性的理解,特别是当结合辅助数据从阿尔马,K2,TESS,和其他设施。这项新的调查将加深我们对近距离双星中的盘演化和行星形成的理解,更广泛地说,将为单星和双星中的盘耗散过程提供线索。
This contribution combines a relatively comprehensive review of the spectroscopic study of the individual component stars and their associated disks in young binary systems, outlines the need for more in-depth studies, and previews the results of a high-spectral and high-angular resolution survey of100 young binaries located primarily in the Taurus and Ophiuchus star forming regions. Observed spectra, synthetic spectral analysis, and preliminary outcomes for 3 systems are presented, illustrating the power and potential of adaptive optics-fed, high-resolution, infrared spectroscopy for our understanding of the dynamical and physical properties of young binary stars and their circumstellar disks and environments, especially when combined with ancillary data from ALMA, K2, TESS, and other facilities. This new survey will deepen our understanding of disk evolution and planet formation in close binaries and, more broadly, will provide clues to disk dissipation processes in both singles and binaries.
