Constructor Detail

Protosystem

public Protosystem(Star s)

Star system contructor. Builds an accretion disc for the specified star.

Parameters:

s - Primary for this system.

Method Detail

coalesce_planetesimals

public void coalesce_planetesimals(Protoplanet p)

Searches the planetesimals already present in this system for a possible collision. Does not run any long-term simulation of orbits, doesn't try to eject bodies...

Parameters:

p - Newly injected accreting protoplanet to test

dist_planetary_masses

public Protoplanet dist_planetary_masses()

Accretes protoplanets from the dust disc in this system.
