Starherd

An interactive Herzsprung–Russell digram for visualizing stellar evolution, based on “Comprehensive analytic formulae for stellar evolution as a function of mass and metallicity” by Hurley, Pols & Tout, and “Zero-age main-sequence radii and luminosities as analytic functions of mass and metallicity” by Tout, Pols, Eggleton, & Han.

Designed and programmed by Xing in 2023, with help from the Shadertoy community. Read my spaghettified code at your own risk.

Warning: Although I’m quasi-confident about the accuracy of the main sequence through the asymptotic giant phases, I have yet to implement the stellar remnants (white dwarfs, neutron stars, and black holes) equations, so any of these occuring should be treated as BS.
