How can an old pulsar have a very short pulsar period, say less than 0.03 seconds?

What will be an ideal response?

Question 2

How does absolute visual magnitude tell us the intrinsic brightness of a star?

What will be an ideal response?

Answer to Question 1

It now appears that the speedy pulsar is an old neutron star that has gained mass and rotational energy from a companion in a binary system. Like water hitting a mill wheel, the matter falling on the neutron star has spun it up to that fantastic rate.

Answer to Question 2

The absolute visual magnitude is the apparent visual magnitude a star would have if it were 10 pc away, and is therefore an expression of the intrinsic brightness of a star.
