Hello!
I just want to know how does a pulsar die, if it dies someday...?

And, #4. Some Pulsars (neutron stars) that are accreting matter from a companion will build enough mass to pass the ~3.2 solar mass "Oppenheimer limit" (upper limit for Neutron stars) and can collapse causing a supernova and/or Black Hole.Janus said:There are three types of pulsars all three are neutron stars:
Rotational
X-ray (or Accretion)
magnetars.
Rotational Pulsars generate their radiation from their rotation, which means as time goes by, their rotation slows. So this type of pulsar "dies" when it has given up all its rotational energy.
X-ray Pulsars form when a neutron star has a binary companion. When the companion, in the course of passing through its life, begins to expand, It can leak material to the Neutron star as accretion matter. It is this accreation matter that provides the energy for the pulses. Such a pulsar would "die" when it ran out of accretion matter. (though the accretion matter can add angular momentum to the neutron star and "spin it up" so that it now becomes a rotational pulsar, which eventually dies in the manner of these types of pulsars.)
Magnetars get their energy from the decay of a very strong magnetic field. So these pulsars "die" when the field has decayed to a low enough level.
A pulsar is a highly magnetized, rotating neutron star that emits beams of electromagnetic radiation from its magnetic poles. It is formed when a massive star collapses in a supernova explosion.
Pulsars eventually run out of energy and stop emitting radiation, but they do not technically "die" in the traditional sense. They continue to exist as a highly dense remnant called a neutron star.
When a pulsar dies, it stops emitting radiation and its intense magnetic field dissipates. The remaining neutron star gradually cools down and becomes a cold, dark object.
No, a pulsar cannot turn into a black hole. Pulsars are formed from the remnants of massive stars that are not massive enough to form a black hole.
The lifespan of a pulsar can vary, but on average, they can live for millions or even billions of years. However, their intense radiation and fast rotation can cause them to spin down and eventually stop emitting radiation in a relatively short period of time.
