I have heard the name of Neutron star,but can't understand why it is called so.

When a heavy star explodes (supernovae), sometimes it's center collapses and creates a very dense ball of neutrons. That center is called a neutron star.

A star having mass of 1.38 times the mass of our Sun explodes as Supernova due to its one gravitational pull.
"1.38 times the mass of our Sun "- this known as Chandrashekar Limit
This is like the general id of Star death .
After this type of death a Star posses the potential of becoming a Neutron Star.
Why so?
When a star loses all its fuel and collapses, it causes the symmetry between electron and proton to break as a result of Enormous pressure of gravity.
For thus atom loses it stability and
Something like this equation happens to the elementary particles(proton',electron)
e- + p+ = neutron + gama ray/আন্টি ইলেক্ট্রন নিউট্রিনো
Huge amount of neutrons form and they resist the pressure of gravity by generating a counter degenerate force
Now to understand how this counter degenerate force/Neutron degeneracy forms you look up to this note

Hey..what is এনটি ইলেকট্রন নিউট্রিনো ???Is it an anti particle of Boson group?

Neutrino isn't Boson. Its Fermion. Gama, Gluon, W+- and Zo are the four Gauge Bosons in the Standard Model which explains 3 main forces of nature;EM, Strong interaction and Beta Decay. But there's another Boson that known as Higgs which stables the Model by providing the reason of how a particle gains its mass.
And Fermions have their Anti but Bosons are antis of themselves. So there's no anti Gama/Gluon. They're just the force carriers in the medium.
And এনটি ইলেকট্রন নিউট্রিনো is in the Fermion section.:)

Ow no no no no no
Its not clear to you my friend :shock:
its still not even clear to the persons who provided its existence :twisted:
Standard Model is the best Model physicists have but its pretty arbitrary with 19 parameters set without proper reason except to take account for the experimental issues. :oops:
In normal case theories predict the outcome but here outcome is made as like it suits the theory :\ :roll:
So surely you're joking , Right? 8-) :lol:

Actually I wanted to say that I have understood that Anti electron neutrino is not boson.....as you write...I haven't ponder it so deeply... :roll:
