How a young star could to shine brightly, even it not having enough mass to generating nuclear reaction????

Answer 1

If your "star" doesn't have enough mass to ignite nuclear fusion then it's not a full blown star. The best it can do is become a brown dwarf star, and these do not shine "brightly."

Answer 2

Hi:

A star doesn't shine it if it don't have the mass for thermonuclear reaction however it can glow for a short time by incandescent gas . this the same thing that happens inside your light blub { but it powered by electricity but not falling Mass however. } when enough mass falling toward the center of the Proto star hits it surface it can produce enough heat to cause the Gases in it to give off light but it will not but a bright as the Star with thermonuclear reaction going but it will last for short time before cooling down to a Gas giant Planet unless it is enough to start the thermonuclear fire going

Answer 3

I'm not sure I understand your question? If a pre-stellar mass (or proto-star) lacks sufficient mass to ignite, it can't shine.

Jupiter, for example, is a proto-star. If it had something like 20% or 30% more mass (I don't remember the exact number) than it does, we would be living in a binary star system and the Jovian moons (Ganymede, Io, Callisto, etc.) would properly be 'planets' instead of moons.
