On the theory of X-ray emission from the extended galactic source Monogem Ring in monoceros constellation

Theoretical description of X-ray radiation from Monogem Ring source in Monoceros based on involving thermal bremsstrahlung of optically transparent hot interstellar gas filling all the huge volume of a superbuble as a main mechanism of X-ray generation is developed. Obtained is analytical description of X-ray spectrum dependence on physical parameters of burst of Monoceros hypothetical supernova (possible original mother of pulsar PSR0656+14) and its remnants as well as from physical parameters characterizing interstellar medium before burst. Resulting formulae are suitable for numerical calculations of spectrum from extremely extended galactic sources of the Monogem Ring type. The results obtained promote elucidation the X-ray radiation nature from the investigated class of sources and can be of great importance in many applications (for example, when studying the nature of background X-ray radiation in the low energy range (h#betta# < or approximately 1 keV), when investigating activity of galaxy nuclei and cascade processes of star formation
