What are White Dwarfs & Black Dwarfs?
And what are Chandrasekhar's limits?
Also I want to know about Neutron Star.

A white dwarf is a small, dense star that is the end stage of a low or medium mass star's life. It is formed when the star runs out of fuel and can no longer sustain nuclear fusion reactions, causing it to collapse and shed its outer layers.
A black dwarf is a hypothetical object that is thought to be the final stage of a white dwarf after it has cooled down completely. Unlike a white dwarf, a black dwarf would no longer emit any light or heat, making it virtually undetectable.
The maximum mass of a white dwarf is about 1.4 times the mass of our Sun, known as the Chandrasekhar limit. This is because any mass above this limit would cause the white dwarf to collapse and potentially become a neutron star or black hole.
A neutron star is formed when a massive star (at least 8 times the mass of our Sun) runs out of fuel and explodes in a supernova. The core of the star then collapses under its own gravity, causing the protons and electrons to combine and form neutrons, creating an extremely dense and compact object.
No, neutron stars are not visible to the naked eye as they are relatively small and emit mostly non-visible radiation such as X-rays and gamma rays. However, they can be observed using specialized telescopes and instruments.
