SP-345 Evolution of the Solar
System
FIGURE 25.6.2.- Below: Angular
momentum transferred to the C cloud as a function of
the mass processed through this cloud. The transfer of momentum is
proportional to the cumulative mass until a saturation is reached,
when almost all the momentum is transferred. Above: Angular velocity
of the Sun after the transfer. When saturation is reached, the solar
angular velocity equals the Kepler velocity of Jupiter. If the
transfer takes place when the Sun is in the deuterium-burning state
with a moment of inertia 200 times the present value, the angular
velocity increases by a factor of 200 as the Sun contracts, producing
the present spin period (25 days) of the Sun when contraction is
completed.
