How does plasma on the Sun is contained?

Answer 1

Gravity and pressure of overlying layers of the sun.

Answer 2

Sometimes called "the fourth state of matter," plasma is a gas composed of charged atoms (ions) and electrons. Plasma is created when a gas absorbs enough heat or other energy to release electrons from their orbits around atomic nuclei.

The hot, bright plasma is contained by closed magnetic fields that have both feet anchored in the photosphere. The plasma is unable to move easily across the magnetic field lines and so there is no contribution to the solar wind from these regions.

Answer 3

There are three ways that the sun contains its plasma: gravity, its own mass (layers) and also magnetically. Plasma plumes will arch over in the magnetic field, they are called prominences.

Sometimes if the plasma is especially energetic (due to too much heat or radiation), it will break loose and go flying out into space. We call this a solar flare or a solar storm. It causes much interference with telecommunications and with power grids.

Answer 4

Plasma, the 4th state of matter, is atoms stripped of some, if not all of their electrons, basically atomic nuclei. Mostly protons. Those protons fuse into helium by a nuclear reaction known as the proton-proton chain, releasing tremendous energy in the process. This nuclear reaction inside the sun's core presses outward against the sheer weight of the sun's "atmosphere", a 700,000 mile-across globe of mostly hydrogen gas. The outward pressure from the core holds the inward pressure of the vast weight of all that hydrogen at equilibrium. The sun won't contract anymore because of the nuclear fusion reaction in its core, and it won't expand anymore because of the weight of the sun on its core. That's how plasma is contained. The high energy light particles/waves, such as gamma rays, x-rays, ultraviolet rays, and visible light, do work their way to the surface and then leave the sun.

Answer 5

Aside from gravitationally, it isn't contained - some of it is even ejected in the form of the solar wind, solar flares, and coronal mass ejections.
