The stellar coronal component of the Galaxy. I. The X-COUNT numerical model.
Abstract
The authors present a computational model for the prediction and analysis of the distribution of galactic X-ray stellar coronal source counts, based on models for the distribution of stars and of interstellar hydrogen in the Galaxy and on known properties of stellar X-ray emission in the solar neighborhood. The model can be, and has been used, for comparisons with unbiased X-ray surveys (equivalent to the deep source counts conducted in the optical), for predictions of stellar X-ray observations with new instruments and to estimate the stellar contribution to the X-ray background.
