Accretion Centers Induced in a Molecular Cloud Core After a Penetrating Collision - Selected Topics of Computational and Experimental Fluid Mechanics - page 486

centers detected in model P 6, while those detected in model P 5 are less visible than
for the other models.
5 Conclusions
Even though this paper has been limited to considering only highly idealized collision
systems, it has been possible to capture and display some of the essential physics of
a collapsing core (the target), that is penetrated by a denser gas core (the bullet).
We here observe that small over-densities are formed behind the perturbation front
left by the bullet along its way digging into the target core. There is still the chance
that these gas condensations may grow to end up as proto-stars. We also observe
that the number and spatial distribution of the accretion centers strongly depends on
the pre-collision velocity. The average mass of the accretion centers do not change
appreciably in the simulations.
