Be grateful these astronomers even made that distinction. They might have just said this stuff (or at least the parts of it that aren’t Hydrogen) was ‘metallic’

Seems like asteroid astrophysicists like to be a bit more specific about this stuff than their stellar and galactic astrophysicist colleagues.
