Introduction to Astronomy provides a quantitative introduction to the physics of the solar system, stars, the interstellar medium, the galaxy, and the universe, as determined from a variety of astronomical observations and models.
This course includes Quantitative introduction to physics of the solar system, stars, interstellar medium, the Galaxy, and Universe, as determined from a variety of astronomical observations and models. Topics: planets, planet formation; stars, the Sun, "normal" stars, star formation; stellar evolution, supernovae, compact objects (white dwarfs, neutron stars, and black holes), plusars, binary X-ray sources; star clusters, globular and open clusters; interstellar medium, gas, dust, magnetic fields, cosmic rays; distance ladder; galaxies, normal and active galaxies, jets; gravitational lensing; large scaling structure; Newtonian cosmology, dynamical expansion and thermal history of the Universe; cosmic microwave background radiation; big-bang nucleosynthesis. No prior knowledge of astronomy necessary. Not usable as a restricted elective by physics majors.
This text includes 25 reading assignments for an introductory astronomy course. They have been modified from the OpenStax Astronomy 2e and College Physics 2e (linked in related resources below) textbooks to order the topics in a logical manner for a one semester course and provide shortened (~10-20 pages) readings intended for biweekly reading assignments. The text also features enhanced treatment of the Newton's Laws, Energy, and Optics content that go beyond the typical introductory astronomy course for non-majors.
Course connections: This content was built for an introductory survey of astronomy course (e.g., PHYS 103), including apparent motions of objects in the sky, light, telescopes, solar system objects, exoplanets, the sun, stars, galaxies, and cosmology. Basic math skills (arithmetic, powers, scientific notation, unit conversions) will be used frequently. This course is designed for students in all majors.
Summaries of the different stages in a star's life cycle, as well as a short summary of the Hertzsprung-Russell diagram.
This humorous OLogy article introduces kids to the Sun. The big star answers 15 questions, including: Your agent told me that you're the biggest star in the universe. Is that true? I know you star types tend to be touchy about age, but how old are you? Actually, I'm curious to know how stars begin. What's your story? Let's turn to a delicate subject. How do stars die? In Hollywood, I meet a lot of people filled with hot air. What gases are inside you?
