AB: The numerical modeling of the self-consistent interaction of the partially ionized local interstellar medium with the solar wind yields detailed estimates of the distribution of neutral particles throughout the heliosphere. The solar wind, and consequently the neutrals, change over the 11 year solar activity cycle. Charge exchange between the neutrals of interstellar origin (and secondary neutrals) and solar wind heavy ions produces characteristic x-ray emission. We calculate a time-dependent global heliospheric model, assuming an idealized 11 year solar wind variation. From this model, we evaluate the time-dependent x-ray (volume) emission and present line-of-sight integrated x-ray intensity predictions. The integration will mix features from different phases in the solar cycle. We also briefly touch on the consequences that ISM variations might have on the x-ray emissions.
