What is believed to be the MOST important factor determining whether a collapsing region (dense core)in an interstellar cloud becomes a single-star or a multiple-star system?

Question

Quizplus · Accepted Answer

The amount of rotation, or spin, plays a crucial role in determining whether a collapsing region becomes a single-star or a multiple-star system. As the cloud collapses, it will continue to spin faster and faster, which can lead to fragmentation and the formation of multiple protostellar cores. If the rotation is strong enough, these cores can form binary or multiple-star systems. Therefore, the amount of spin is considered the most important factor in determining the outcome of star formation in collapsing regions.
