The Fundamentals of Stellar Astrophysics
George W. Collins II · Ohio State University
This book offers a rigorous, theory-driven overview of stellar astrophysics, from the physics of matter, energy generation, and transport to full models of stellar structure and evolution. It covers main-sequence and post–main-sequence stars, relativistic and rotating stars, pulsations, and stellar atmospheres, linking fundamental physics to observable stellar properties and spectra.

Physics 9HC: Introduction to Waves, Physical Optics, and Quantum Theory
Tom Weideman · University of California, Davis
Physics 9HC is the third in the "honors" introductory physics series. It starts by covering the general topic of waves, and applies the principles learned to the study of light (physical optics). The lines are then blurred between light and particles in the realm of the very small, resulting in an introduction to the quantum theory.

University Physics II: Thermodynamics, Electricity, & Magnetism
OpenStax · LibreTexts
This text explores thermodynamics, electricity, and magnetism, building on the foundations of mechanics. You’ll study heat and energy, electric charges and circuits, magnetic forces, and the unifying principles of Maxwell’s equations and electromagnetic waves. With examples and practice problems, this text provides the tools to understand and apply these essential ideas in science and engineering.
