Here are some interactive simulations I’ve built, often with the help of Claude.
See how stars, initially in the main sequence, evolve. Inspect their internal layers, composition, macroscopic properties (temperature, density, luminosity etc) as they leave the main sequence and eventually die. ( GitHub)
Watch as two black holes of different masses and spins orbit each other and emit gravitational waves. Listen to the gravitational wave pitch as they eventually merge into one final black hole. ( GitHub)
