the weakening of the magnetic field of a migrating sun spot towards the equator allows an influx of coronal plasma. a magnetic bubble forms with increasing pressure. with sufficient pressure this bubble bursts and ejects coronal mass.

The sun has a substantial magnetic field and this field sometimes pokes out of the solar surface. It's like having a shrink-wrapped ball of string (the magnetic field) with occasional threads poking out of holes in the shrink- wrap. Plasma particles from the sun are trapped in this magnetic field and the light emitted by this plasma reveals the arched shape of the magnetic field. If electric currents flow along the arch, it twists up, and when it becomes too twisted, it erupts.. and that eruptions are coronal mass ejections.. got it??

If I'm not mistaken, the gases inside the stars don't burn steadily, but there are periods of stronger and periods of weaker activity. There are coronal mass ejections at all times, but sometimes they're unusually strong because of their irregular nature.

They develop from the black sun spots, which are much cooler than the surrounding mass and interact strongly with the suns magnetic field. That interference causes bursts that eject massivly from that spot.

the massive explosions in the outer region of the sun expell plasma from the surface. Then the suns' gravity pulls it back.

Ah well.It is a chaotic event closely related to simple boiling.It can be like a super saturated solution suddenly crystalizing.

We really don't know. But scientists are studying the Sun to try and find out.
