X-ray emission from comets is now a well-established phenomenon. Satellites like BeppoSax and Extreme Ultraviolet Explorer (EUVE) and, in particular, RA~¶ntgen Satellite (ROSAT) have detected 15 comets in x-rays. However, the most significant advance in our understanding of x-ray emission from comets was the Chandra X-ray Observatory (CXO) observation of comet Linear 1999 S4 and, in particular, the spectrum contain some 13,500 photons. Using our unified plasma model, we had previously predicted that the x-ray spectrum of a comet should be a combination of bremsstrahlung and discrete emission lines. We have now combined our model with the Atomic Data and Analysis Structure (ADAS) to calculate the expected spectrum. We find an almost perfect agreement between the observed CXO spectrum and our model which is based on just carbon, nitrogen and (mainly) oxygen x-ray lines on a bremsstrahlung continuum that accounts for 2/3 of the total x-ray emission.
