friend- a star begins to form when the gasses and dust particles in the nebula clump closer together
enemy- it gains mass. over time, the star will form a gravitational center.
They are not. Both have gravity which influences other objects in space. That's pretty much it.
When the gravity of a neutron star overcomes the degeneracy pressure of the neutrons, the neutron star collapses into a black hole.
When a star runs out of energy, its mass is so great that the remaining energy cannot force the outer edges of a star away from its core, so the gravity causes the star to implode on itself.
The gravity of the Sun (or star) keeps them in orbit.
The most immense gravity for it's size of any single object in the universe. If it had been a slightly larger star before it went supernova and wound up as a neutron star, it would have collapsed into a black hole - where not even light could escape it's gravity.
Mainly in that gravity is involved in both cases.

Behind Enemy Lines - Star Trek - was created in 1998.
Depends on the star, and how close you are to the star.
the star's size
There is no force opposite to gravity (except in a star where the light pressure from the fusion in the core holds the star up against gravity).
no
Gravity.
The remains of a massive star pulled into a small volume by gravity?
Gravity pushes and pulls on a star, balancing it out so it doesn't explode.
A star is a sphere of gas held together by its own gravity.
White Star Lines was boat company that built the largest ship in her time the Titanic. The White Star Line main enemy was Cunard boat company.
