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

INT 9512791 Richards这个由弗吉尼亚大学的Mercedes Richards博士和捷克科学院天文研究所的Pavel Koubsky博士共同开展的美国-捷克研究项目，将重点测试拟议的双星Be星(具有发射线的B型星)模型的实用性。如果他们成功了，结果应该有助于形成一幅关于两类Be恒星的统一图景，一类是遮挡算法恒星(通常在轨道平面上侧视)，另一种是非遮挡算法恒星。在这项工作中，研究人员将对经典阿尔戈尔进行广泛的光学和紫外光谱研究，以解释非日食阿尔戈尔候选者的光谱。他们希望证明，目前明显缺乏的不黯然失色的算法是一种选择效应。总体而言，这些发现应该会增加我们对这些相互作用的双星中的恒星周围物质的三维结构的理解，这些双星位于轨道平面之上和之下。这个恒星天文学项目通过使美国和东欧的顶尖专家能够将互补的人才结合在一起，并在共同感兴趣和有能力的领域汇集研究资源，实现了促进基础科学知识的计划目标。?？

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. ??
