Answer 1

Answer:

A pulsar is formed when a massive star collapses exhausts its supply of fuel. It blasts out in a giant explosion known as a supernova, the most powerful and violent event in the universe.

A magnetar is a type of neutron star believed to have an extremely powerful magnetic field (∼1013 to 1015 G, ∼109 to 1011 T). The magnetic field decay powers the emission of high-energy electromagnetic radiation, particularly X-rays and gamma rays.

A neutron star is the collapsed core of a giant star which before collapse had a total mass of between 10 and 29 solar masses. ... They result from the supernova explosion of a massive star, combined with gravitational collapse, that compresses the core past white dwarf star.

Answer 2

Explanation:

1. What is Pulsar(Star)?

• Pulsars are rotating neutron stars observed to have pulses of radiation at very regular intervals that typically range from milliseconds to seconds. They have very strong magnetic fields which funnel jets of particles out along the two magnetic poles.

2. What is magnetar?

• Another type of neutron star is called a magnetar. In a typical neutron star, the magnetic field is trillions of times that of the Earth's magnetic field. however, in a magnetar, the magnetic field is another 1000 times stronger.

3. What is neutron star?

• Neutron stars are formed when a massive star runs out of fuel and collapses.
• Despite their small diameters : about 12.5 miles (20 kilometers): neutron stars boast nearly 1.5 times the mass of our sun, and are thus incredibly dense.
• Neutron stars pack an extremely strong gravitational pull, much greater than Earth's.
• Since neutron stars began their existence as stars, they are found scattered throughout the galaxy in the same places where we find stars.
• Many neutron stars are likely undetectable because they simply do not emit enough radiation. However, under certain conditions, they can be easily observed.
