Stellar Smash!

A simulation of a stellar collision.
NOTE: This uses a metallicity Z=0.02. You can monitor a run in progress using the links below, which open new windows. Happy space adventures!

Would you like to collide two stars?
Enter respective masses of each star:
         solar masses

         solar masses

Enter desired final time:

Enter the number of particles for each star:

Enter the periastron distance of the two stars:
         solar radii.

Enter the relative velocity of the stars at an infinite distance apart:
         solar units.

Solar units means G=Msun=Rsun=1.
For example: the unit of velocity is Sqrt(G*Msun/Rsun)=437 km/s.

OR enter the relative velocity in km/s:
