Understanding Stellar Structure and Evolution: A Course in Astrophysics

This course delves into the physical principles governing the structure and evolution of stars. Key objectives include understanding stellar formation, evaluating evolutionary stages, and diagnosing stellar atmospheres via observational techniques. Required reading includes "Physical Principles, Structure and Evolution" by C.J. Hansen et al. and supplementary material on stellar atmospheres by David F. Gray. Assessments consist of weekly homework, a modeling project, and exams, with a focus on developing a comprehensive understanding of stellar dynamics.
