This is a scientifically accurate simulator which shows how stars evolve over time. How to use this simulation: Press the green flag, type in the star's starting mass in solar masses, and hit enter. The button on the lower right is pause/play. Supports stars from 0.05 to 100 solar masses. UPDATE HISTORY: June 7, 2019 - version 0.23 -improved how the glow effect's size changes relative to brightness and zoom June 6, 2019 - version 0.22 -reworked mass loss equations for main sequence and supergiant stars -black holes now have an accretion disk graphic -fixed a bug causing nebulae to appear during black hole formation June 5, 2019 - version 0.21 -added luminosity variable -star now has a glow effect -minor tweaks to temperature and radius equations
