U.S.-Czech Astronomical Research on Morphologies of Eclipsing and Non-eclipsing Algols

INT 9512791理查兹 这个美国-弗吉尼亚大学的Mercedes理查兹博士和捷克科学院天文研究所的Pavel Kebrsky博士之间的捷克研究项目将侧重于测试一个拟议的Be双星（具有发射线的B型星）模型的效用。 如果他们是成功的，结果应该有助于两类Be星的统一图像，食Algols（通常在轨道平面上观察）和非食Algols。 在这项工作中，研究人员将对经典的大陵五进行广泛的光学和紫外光谱研究，以解释非食大陵五候选者的光谱。 他们希望证明，目前明显缺乏不食的Algols是一种选择效应。 总的来说，这些发现应该增加我们对这些相互作用的双星中星周物质的三维结构的理解，在轨道平面上方和下方。 这个恒星天文学项目实现了促进基础科学知识的计划目标，使美国和东欧的领先专家能够在共同感兴趣和能力的领域联合收割机互补人才和集中研究资源。 ??

INT 9512791 Richards This U.S.-Czech research project between Dr. Mercedes Richards of the University of Virginia and Dr. Pavel Koubsky of the Astronomical Institute of the Czech Academy of Sciences will focus on testing the utility of a proposed model for binary Be stars (B-type stars with emission lines). If they are successful, results should contribute to a unifying picture of two classes of Be stars, eclipsing Algols (typically viewed edge-on, in the orbital plane) and non-eclipsing Algols. In this effort, the researchers will undertake extensive optical and ultraviolet spectroscopic studies of classical Algols to interpret the spectra of non-eclipsing Algol candidates. They expect to prove that the present apparent paucity of non-eclipsing Algols is a selection effect. Overall, these findings should increase our understanding of the three-dimensional structure of circumstellar matter in these interacting binaries, above and beneath the orbital plane. This project in stellar astronomy fulfills the program objective of advancing basic scientific knowledge by enabling leading experts in the United States and Eastern Europe to combine complementary talents and pool research resources in areas of mutual interest and competence. ??
