Does the Initial Rate of Star Formation Have Any Effect

question 137

Multiple Choice

Does the initial rate of star formation have any effect on the type of galaxy that is formed from a pregalactic 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. 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.
