⚙ Under the hood

Complete guide to astrophysics: watch a star of chosen mass move across a 3D Hertzsprung-Russell diagram from the main sequence to red giant and final remnant (white dwarf, neutron star or black hole), plus a compact-object merger with gravitational-wave ripples and a dark matter halo overlay.
