SUMMARY
The discussion focuses on calculating the new rotational period of a star after its diameter shrinks to 0.610 times its original size, given its mass of 1.170×1031 kg and an initial rotation period of 28.30 days. The key principle to apply is the conservation of angular momentum, which states that the product of the moment of inertia and angular velocity remains constant if no external torques act on the system. By using this principle, one can derive the new period of rotation after the diameter change.
