My name is Emerica and I have taken 2 exams with u and I really like to contact you about other programs that are done in your program. I want to know if you have institute or college that offers nursing programs, if so, what's the requirements.
When the stars go out. Eventually, a main sequence star burns through the hydrogen in its core, reaching the end of its life cycle. At this point, it leaves the main sequence.Stars smaller than a quarter the mass of the sun collapse directly into white dwarfs.White dwarfs no longer burn fusion at their center, but they still radiate heat.ventually, a main sequence star burns through the hydrogen in its core, reaching the end of its life cycle.

Tell me more about the Sun. A star's life is a constant struggle against the force of gravity. Gravity constantly works to try and cause the star to collapse. The star's core, however is very hot which creates pressure within the gas.This pressure couteracts the force of gravity, putting the star into what is called hydrostatic equiliburum.he cloud doesn't collapse into just one large star, but different knots of material will each become it's own protostar. This is why these clouds of material are often called stellar nuseries  they are places where many stars form. As the protostar gains mass, its core gets hotter and more dense.
