A close encounter between two galaxies is LEAST likely to trigger starburst in which type of galaxy?

Question

Quizplus · Accepted Answer

Elliptical galaxies have older populations of stars with low levels of gas and dust, making them less likely to experience starburst activity. In contrast, spiral and irregular galaxies have higher levels of gas and dust, providing the necessary raw materials for star formation. Barred spiral galaxies fall somewhere in between, with their star formation activity depending on the specific characteristics of each individual galaxy. Therefore, the answer is A) elliptical as they are least likely to experience starburst activity during a close encounter with another galaxy.
