Abstract:
The collapse of a spherically symmetric, self-gravitating, isothermal,
protostellar cloud has been described in terms of hydrodynamics by several
authors. One of the solutions found provides initially flat behaviour of
the density in the cloud's interior. (This specific interior herein is
referred to as "the central plateau".) This paper gives an analytical
solution - in the form of a power series - of the equations of motion of
a test point-like mass body, located within the central plateau. The solution
reducing computational time can be useful in studying the dynamics of a huge
number of bodies in a collapsing protostellar cloud (in studying the dynamics
of cometary nuclei in the collapsing protosolar nebula, for example).
