Unformatted text preview: Heavy elements enter the primordial nebula So far, to this point, there is little to distinguish high and low mass nebula theories. A lot of the difference between them, however, resides in the mechanism for explaining where the angular momentum goes, since all theories of collapse show a very fast spin rate must be built up as the star is formed. To get from that state to our current situation where the sun spins relatively slowly and most of the angular momentum of the solar system resides in the planets (particularly Jupiter) requires a lot of dissipation of the angular momentum to have occured, and it seems only in the early days of formation of the system could this have happened. It is one of the major difficulties of theories of solar system formation to explain where the angular momentum went. Low Mass Nebulae Formation from a "low-mass" nebula means that the mass of the cloud which contracts to form the star and planets is around 1.1 times the mass of the star, so in the case of the solar system, 1.1 the star and planets is around 1....
