摘要:

单线光谱双星御夫座的观测为研究这颗定义不清的伴星提供了机会。我们在CHARA阵列上使用MIRC光束组合器在日食进入期间创建干涉图像。我们的研究结果表明,食体是一个黑暗的磁盘,是不透明的和倾斜的,因此排除了系统的替代模型。这些数据限制了组成部分的几何和质量,提供了F星不是大质量超巨星的证据。

英文摘要:

Eclipses of the single-line spectroscopic binary star, epsilon Aurigae, provide an opportunity to study the poorly-defined companion. We used the MIRC beam combiner on the CHARA array to create interferometric images during eclipse ingress. Our results demonstrate that the eclipsing body is a dark disk that is opaque and tilted, and therefore exclude alternative models for the system. These data constrain the geometry and masses of the components, providing evidence that the F-star is not a massive supergiant star.
