A screenshot and video from one of our first tests of the Stellar Evolution code for Universe Sandbox 3.
VideoA very rough video of Stellar Evolution. This is an early implementation of a HR (Hertzsprung-Russell) diagram:
http://en.wikipedia.org/wiki/Hertzsprung%E2%80%93Russell_diagramWe're working on adding supernova explosions so that when the star disappears (as it currently does in the video) it will explode magnificently and leave behind a black hole, neutron star, or white dwarf.
Universe Sandbox 3.0 HR diagramImageThe y axis represents starting mass (big at the top, small at the bottom) and the x axis represents time (starts on the left and advances to the right).
You can see how some of the blue stars turn in to orange giants later in life and the row of white stars (with a starting mass equal to our own sun) grows as it gets older.
This screenshot and video represents Eric's work on implementing scientifically accurate stellar evolution and the graphics work of Georg.
Universe Sandbox 3 is a major update due out later this year for both Windows and Mac. This is a full rewrite of Universe Sandbox in a new 3D engine and will be a free update to everyone who has ever purchased Universe Sandbox through this website or on Steam.
