9314931 Bell The P.I. will continue his program of research in the area of stellar evolution. Theoretical calculations concerned with stellar atmospheres, stellar interiors and nucleosynthesis will be made. Observations of stars in globular star clusters and field stars, including Cepheid variable stars, will be made for comparison with the calculations. The goals are to improve our understanding of the properties of stars and how they evolve with time and to create stellar spectral libraries needed to understand both the stellar population of our galaxy and the evolution of galaxies. ***

9314931贝尔私人侦探将继续他在恒星演化领域的研究计划。本课程将进行有关恒星大气、恒星内部和核合成的理论计算。对球状星团和场星，包括造父变星的观测，将与计算结果进行比较。其目标是提高我们对恒星的性质以及它们如何随时间演化的理解，并创建理解我们银河系的恒星数量和星系演化所需的恒星光谱库。***
