Comparing stars

The course aims to help learners understand the Hertzsprung-Russell diagram, stellar masses, stellar evolution, and observing through the interstellar medium. By the end of the course, students will be able to construct the H-R diagram, identify the main classes of stars, explain the distribution of stars on the diagram, and explore the interstellar space using stars as probes. The teaching method includes theoretical explanations, practical examples, and observational techniques. This course is designed for individuals interested in astronomy, astrophysics, or space science.
