NGC 6302: ionized by a very hot star or by a wind?

Lines of very highly ionized silicon recently discovered in the type I planetary nebula NGC 6302 implied a central star temperature of 450,000 K assuming that the high ionization lines were the result of photoionization. This is the highest central star temperature ever reported for a planetary nebu...
