Simon, Michal 9417191 In the nearby Taurus and Ophiuchus star forming regions, most of the stars are formed in multiple systems. Binary formation appears to be the dominant mode of star formation. The first goal of this research is to investigate whether this result is a peculiarity of either the class of young stars observed or of the star forming region. Very large, new samples of X-Ray selected young stars in the Orion OB association and Corona Australis will be surveyed for multiplicity. The second goal is to measure the most fundamental stellar parameter, the mass, in at least some of the young star binaries. High resolution IR spectroscopy offers the possibility of identifying low mass companions that elude detection in the visible. The third goal is to study the early evolution of binaries and their inner disks by angularly resolved IR spectroscopy. ***

Simon，Michal 9417191在附近的金牛座和蛇夫座星星形成区，大多数恒星是在多个系统中形成的。 双星形成似乎是星星形成的主要模式。 这项研究的第一个目标是调查这一结果是否是观测到的年轻恒星或星星形成区域的特殊性。 非常大的，新的样本的X射线选择的年轻恒星在猎户座OB协会和南冕座将调查的多样性。 第二个目标是测量最基本的恒星参数，质量，至少在一些年轻的星星双星。 高分辨率红外光谱提供了识别在可见光中逃避检测的低质量伴随物的可能性。 第三个目标是通过角分辨红外光谱研究双星及其内部盘的早期演化。 ***
