No. An event horizon is an area where even light cant escape so only black holes have it
A black hole has an event horizon, beyond which nothing can escape, including light. Neutron stars also have an event horizon, called the "surface" or "crust," which marks the boundary within which matter is crushed by extreme gravity. White dwarfs, being less massive, do not have an event horizon.
No. Only black holes have event horizons.
The size of a black hole, as defined by the size of the event horizon, depends on the mass of the black hole and its electrical charge. The diameter of the event horizon is directly proportional to the black hole's mass. Adding electrical charge decreases the size of the event horizon.
No, white dwarfs do not have an event horizon. Event horizons are a characteristic feature of black holes, where the gravitational pull is so strong that not even light can escape. White dwarfs are dense stellar remnants, but they do not have the extreme gravity needed to form an event horizon.
The "boundary" you're probably thinking of is called the event horizon. Past this point, the escape velocity of the black hole exceeds the speed of light, meaning nothing, including light, can escape it.
If you mean a giant star, no.
No, they do not.

That refers to a black hole - but a black hole is not exactly a star.
No planet has an event horizon. A black hole has an event horizon; it is the radius within which light cannot escape.
Event Horizon was released on 08/15/1997.
The Production Budget for Event Horizon was $60,000,000.
The duration of Event Horizon - film - is 1.58 hours.
It seems you are referring not to any collapsed star, but a black hole. The "event horizon" is the area from which nothing can escape.
The giant star
Event Horizon - film - was created on 1997-08-15.
