Stellar Astrophysics Dataset
How stars form, live, forge the elements and die — the stellar processes (formation, main sequence, giant branches, mass loss, core collapse), the nucleosynthesis pathways (pp chain, CNO cycle, triple-alpha, s- and r-process), and the physics concepts (HR diagram, degeneracy pressure, IMF, metallicity, populations, binaries).
