The sudden eruption from the surface of a star is called a plasma ejection. It is also known as a coronal mass ejection. They can be very dangerous if they happen to eject toward a planet nearby.
Composite volcanoes are highly variable in what they erupt. Most often, eruptions will release clouds of ash, pumice, and rock fragments. In some cases they fountain or extrude lava.
