  • The resulting magnesium silicate recrystallizes to form forsterite and silica in the temperature range 800-850° C, as an exothermic process.

    Geology of asbestos

  • The existence of forsterite in a star like HOPS-68 is not entirely without precedent; the crystals have been found in the vicinity of young stars before, but never so high up - and never behaving like rain before.

  • But that's not a problem if the forsterite wasn't created there at all.
