A neutron star is formed by the gravitational collapse of a massive star after a supernova. It has a mass of 1-3 times the sun's mass but is only about 20 km in diameter, making it incredibly dense. The first neutron star was discovered in 1967 by Jocelyn Bell, a graduate student who discovered a pulsar, a type of neutron star that emits beams of electromagnetic radiation. Neutron stars come in different types, including pulsars which are highly magnetized and rotating neutron stars that emit beams, and magnetars which have extremely powerful magnetic fields that power their emission of high-energy radiation.
2. WHAT IS A NEUTRON STAR
• A neutron star is a type of
compact star that can result
from the gravitational collapse
of a massive star after
supernova.
• Neutron stars are formed by
death of stars.
5. Discovery of neutron star
• The first neutron star
was discovered by
24-year-old graduate
student Jocelyn bell
in 1967.
• she discovered the
first pulsar a type of
neutron star.
7. Facts about neutron star
• It’s mass is in between one and three
sun.
• Neutron star is about 20 km in diameter
• It’s mass is so dense that electron enters
the nucleus and forms a neutron by the
process of electron capture
• e + p
9. Pulsar
• A Pulsar is a highly
magnetized,
rotating neutron star.
• That emits a beam
of electromagnetic
radiation.
• This radiation can
only be observed
when the beam of
emission is pointing
toward Earth
10. Magnetar
• A magnetar is a type
of neutron star with
an extremely
powerful magnetic
field.
• The magnetic field
decay powers the
emission of high-
energy
electromagnetic
radiation, particularly
X-rays and gamma
rays.
12. Neutron star Vs black hole
• Neutron star stand
nothing infront of
black hole
• Because gravity of
black hole is much
more the that of
neutron star
14. Nearest neutron star
• Astronomers using X-ray telescope
have detected a neutron star within
250 to 1,000 light-years of Earth,
making it the closest neutron star
ever known.
• There is zero possibility that a
neutron star will going to hit the
earth.
For the formation of black hole the size of the star should be 30 times more than that of sun.
If the size of the star is less than 30 times of that of the sun then it will be converted into neutron star
