These outbursts, along with coronal mass ejections (CMES), which are explosions of blazingly hot plasma, can be incredibly destructive to planets orbiting red dwarf stars.

Destructive to Planets

Stripping them of their atmospheres and emitting enough radiation to boil away liquid water even in the so-called habitable zone around them.

Which is the area around a star in which liquid water can exist on a planet's surface.
