Multiple Choice
Does the initial rate of star formation have any effect on the type of galaxy that is formed from a pre-galactic gas cloud?
A) No, the initial rate of star formation determines the size of the galaxy. A high initial rate of star formation means that many stars have formed a large galaxy before the remaining gas and dust dissipate and star formation ceases. But a galaxy of any type is equally likely to form.
B) Yes, a high initial rate of star formation uses up the gas and dust before it has a chance to settle into a disk. So this results in an elliptical galaxy.
C) Yes, a high initial rate of star formation produces an early generation of stars that evolve and send out more gas and dust to form a disk and to perpetuate star formation. So this results in a spiral galaxy.
D) Yes, an initially high rate of star formation produces many high-mass stars that explode and send out shock waves to trigger the formation of other stars. This chaotic situation results in an irregular galaxy.
