Technical Narrative: This proposal will continue the joint India-U.S. research program in theoretical astrophysics begun in 1987 between the Tata Institute and the University of Chicago. Dr. S. M. Chitre of the Tata Institute of Fundamental Research, Bombay, India and Dr. David Schramm of the University of Chicago are the co-principal inves- tigators. The main focus of the program is nuclear astrophysics with a fitting emphasis in the past three years on the supernova that occurred on February 23, 1987 (SN1987A). For a field that has been theoretically dominated in the past, this event has added a new dimension through the observations that have occurred, especially in the Large Magellanic Cloud. The proposed studies of the supernova are expected to address the following issues: 1) How does a type II supernova explode? 2) What are the number, orbital period distribution and mass ratios of binary stars in the Large Magellanic Cloud? 3) How many pulsars are there in the galactic globular cluster systems and what is their evolutionary origin? The proposed research will address also the recent interest in the role of the quark-hadron phase transition in the early universe, and ultra-high energy cosmic ray interactions. Scope: The two scientists who are eminent in the field in their respective countries plan to continue their collaboration in theoretical astrophysics studying nuclear structure in the early universe and in a contemporary high energy environment, the massive stars that explode as supernovae. Specifically, the focus is nuclear astrophysics, supernovae, and the quark-hadron transition in the early universe. The results of advances in this field are wide- ranging in the understanding of the physics of matter, astronomy and astrophysics.

技术叙述：该提案将继续进行印度 - 美国联合。 理论天体物理学的研究计划始于1987年塔塔学院和芝加哥大学之间。 印度孟买塔塔基础研究所的S. M. Chitre博士和芝加哥大学的David Schramm博士是联合主管。 该计划的主要重点是核天体物理学，在过去三年中，其重点是1987年2月23日（SN1987a）发生的超新星。 对于过去一直在理论上统治的领域，该事件通过发生的观察结果增加了一个新的维度，尤其是在大型麦哲伦云中。 预计对超新星的拟议研究将解决以下问题：1）II型超新星如何爆炸？ 2）大麦芽云中二进制恒星的数量，轨道周期分布和质量比是多少？ 3）银河球状簇系统中有多少个脉冲星，它们的进化起源是什么？ 拟议的研究还将解决对早期宇宙中夸克 - 戴隆相变的作用以及超高的能量宇宙射线相互作用的最新兴趣。 范围：在其各自国家中著名的两位科学家计划继续在理论天体物理学中进行合作，研究早期宇宙和当代高能环境中的核结构，这是爆炸的超新星。 具体而言，重点是核天体物理学，超新星和早期宇宙中的夸克 - 戴隆过渡。 该领域进步的结果广泛 - 了解物质，天文学和天体物理学的理解。
