Answer:
The next step in the process is the formation of a prestar core.
Explanation:
After the interstellar dust and gases concentrate in a determined zone gravity starts to unite them and they gather forming a core that is united by gravity. The surroundings start to disperse and the remaining dust starts to expand in the neighboring regions forming different levels of density in dust and gravity force. Which lately will form the satellites, planets or spacial objects that will be bound to the future sun. It is only the second step in the formation of the new star.
