A previous paper (1997. T. G. Northrop, C. M. Lisse, M. J. Mumma, and M. D. Desch.Icarus127,246–250.) established that the total X-ray radiation intensity from Comet Hyakutake can be attributed to electron-neutral bremsstrahlung by using an electron energy spectrum of the shape seen by Vega 2 at Halley, but otherwise using solar wind and cometary parameters characteristic of Hyakutake. In this paper we find that the predicted photon spectrum also agrees with Hyakutake observations, insofar as they are known, in both shape and intensity. |
