A Concise Introduction to Astrophysics

Comprehensive lecture notes covering celestial mechanics, stellar physics, and the tools astronomers use to study the cosmos. A thorough starting point for undergraduates.

Institute of Theoretical Astrophysics

A rigorous course on astrophysical fluid dynamics, radiative transfer, and self-gravitating systems. Aimed at students ready to derive the equations behind modern astrophysics.

Dr. Romain Teyssier

A clear introduction to the fluid dynamics that governs stars, accretion disks, and the interstellar medium. These lecture notes build the equations of astrophysical flows from the ground up.

Gordon I. Ogilvie

A short guide to the elements of stellar physics, from the main sequence to the equations of stellar structure. A concise resource for grasping how stars work.
