摘要
The first observation of the far UV, emission line spectrum of a supernova remnant (SNR), namely a filament in the Cygnus Loop, suggests that carbon, initially depleted in the gaseous phase by a factor of 10, is progressively returned to this phase, presumably by destruction of graphite grains in the high temperature, post-shock region. © 1979 Nature Publishing Group.
