Explanation:
Pulsar is also called as<u> neutron stars or white dwarfs.</u> These are formed after the supernova explosion. Their mass is higher than a normal star. And the most different thing we find in pulsar is that, in a pulsar the proton and electrons combine themselves to form a neutron. That's why this is also called as neutron star.
