U.S.-Austria Cooperative Research on the Seismology of StarsFrom the Main Sequence to White Dwarfs.

该奖项支持德克萨斯大学奥斯汀分校的Donald Winget博士和其他人(包括研究生)与维也纳大学天文研究所的Michel Breger博士及其团队在天体物理学研究方面进行合作。这两个研究小组一直在运营两个独立的国际望远镜网络，用于测量非常不同年龄的恒星的特征：Delta Scuti网络(奥地利)和全地球望远镜网络(德克萨斯州)。这两个网络的目标相似，都是将复杂脉动恒星的亮度变化完全分解为它们的分量频率，用于恒星内部的地震学研究。然而，这些网络目前在其覆盖的频域上是完全不同和互补的。此处建议支持的协作的目标是集成这两个网络以及软件、人员和分析方法。然后，参与者将能够同时测量几颗处于恒星演化极端状态的选定恒星。为这一提议提供基础的工作通过对太阳的研究，在恒星物理领域开辟了新的天地。所采用的技术和方法通过使用观测网络和应用地震学理论来探索恒星的内部结构，开启了恒星动力学和演化研究的一个全新水平。扩大的合作为推进这项研究提供了一个独特的机会。

This award supports Dr. Donald Winget and others (including graduate students) of the University of Texas at Austin to collaborate in astrophysics research with Dr. Michel Breger and his group at the Institute of Astronomy, University of Vienna. The two research groups have been operating two independent international telescope networks for measuring features of stars of very different ages: the Delta Scuti Network (Austria) and the Whole Earth Telescope Network (Texas). The networks are similar in their goal of completely resolving the brightness variations of complex pulsating stars into their component frequencies for seismological study of stellar interiors. However the networks are currently completely different and complementary in the frequency domains that they cover. The goal of the collaboration proposed for support here is to integrate the two networks and software, personnel, and analytical methods. The participants will then be able to measure simultaneously several selected stars in extreme states of stellar evolution. The work that provides the basis for this proposal has broken new ground in the field of stellar physics through studies of the Sun. The techniques and approach being employed have opened a whole new level of study of stellar dynamics and evolution, by probing the internal structure of stars using networks of observations and applying seismological theory. The expanded collaboration offers a unique opportunity to advance this research.
