Abstract
The assumption that the entire velocity rotation curve is due to a massive, spherical galactic halo (massive halo hypothesis) is used to construct a model of discrete soft x-ray emitting sources. Hot white dwarfs and flaring red dwarfs were found to have sufficient luminosity to account for the observed x-ray intensity. However, the distribution of these sources as dictated by the massive halo hypothesis is such that the observed latitude dependence of the x-ray intensity is not reproduced. Emission from a hot coronal gas also fails to reproduce the observed latitude dependence of the soft x-ray intensity; however, the crudity of the model of the hot coronal gas precludes any definite conclusions.
