U.S.-Italy Workshop: Angular Momentum and Mass Loss for Hot Stars; Ames, Iowa, October 1989

该奖项将支持一个由教授 李·A爱荷华州州立大学的威尔逊和罗伯托教授 的里雅斯特大学的斯塔利奥。 研讨会将是 第二个在一系列的动力学现象在恒星和环境， llar环境。 第一次是在的里雅斯特举行的脉动 和质量损失这一节讲的是角动量和质量损失 被关押在爱荷华州的艾姆斯。 这一系列的目标 研讨会的目的是探索和促进基础研究 恒星天体物理学的问题。 恒星天体物理学尚未解决的基本问题包括： 角动量对恒星结构和演化的影响， 的性质和效率的过程中， 动量在恒星内部重新分配，并从恒星中丢失， 恒星自转在增加或推动恒星质量 损失 关于角动量和质量损失专题的讲习班 是及时的，因为：（1）计算代码纳入恒星 旋转恒星模型开始发展;（2） 最近没有关于这个问题的会议，因为它 适用于质量更大、旋转更快的恒星;（3） 旋转作为质量损失和影响 脉动，这反过来又会影响质量损失，才刚刚开始， 赞赏;和（4）利用快速的观察技术 旋转来研究早型星的脉动性质， 正在开发中。 该主题特别适合于 在美国的支持下，意大利计划，因为许多重要的 这两个国家正在开展这方面的活动。

This award will support a workshop jointly organized by Professor Lee A. Willson of Iowa State University and Professor Roberto Stalio of the University of Trieste. The workshop will be the second in a series on dynamical phenomena in stars and circumste- llar environments. The first one was held in Trieste on pulsation and mass loss; this one will be on angular momemtum and mass loss and is being held in Ames, Iowa. The objective of this series of workshops is to explore and stimulate research in fundamental problems of stellar astrophysics. Fundamental unsolved problems of stellar astrophysics include the effects of angular momentum on stellar structure and evolution, the nature and efficiency of the processes by which angular momentum is redistributed within and lost from stars, and the role that stellar rotation plays in enhancing or driving stellar mass loss. A workshop on the topic of angular momentum and mass loss is timely because: (1) computational codes incorporating stellar rotation into stellar models are beginning to be developed; (2) there has not been a meeting recently concerning this topic as it applies to the more massive, rapidly rotating stars; (3) the importance of rotation as a factor in mass loss and in affecting pulsation, which in turn affects mass loss, is just beginning to be appreciated; and (4) observational techniques making use of rapid rotation to study pulsation properties of early type stars are also being developed. The topic is particularly appropriate for support under the U.S.- Italy Program since much of the important activity in this area is being carried out in these two countries.
