Survey of the Supernova Remnant Kes 79 by Results of 13CO and Methanol Observations

The molecular environment of the galactic supernova remnant Kes 79 by results of 13CO and methanol observations was studied. The 13CO spectral line broadening at velocities +90 and +105 km/s in the region of SNR-molecular cloud interaction is first revealed. Such a line broadening can be interpreted...

M. Zubrin, S. Y. Myshenko, V. V. The molecular environment of the galactic supernova remnant Kes 79 by results of 13CO and methanol observations was studied. The 13CO spectral line broadening at velocities +90 and +105 km/s in the region of SNR-molecular cloud interaction is first revealed. Such a line broadening can be interpreted as a new evidence of SNR Kes 79 interaction with molecular clouds. The broadening at velocity +105 km/s was observed all over the SNR area. The region with broadened spectral line at velocity +90 km/s is located towards the north-eastern boundary of the SNR. A new methanol maser was discovered towards the OH molecule emission region previously detected in Kes 79. Presumably, the maser can be associated with the interaction of molecular cloud, moving at line-ofsight velocity +90 km/s, and SNR. The intensity of the detected maser varies with time. Проведено исследование молекулярного окружения галактического остатка сверхновой (OCH) Kes 79 по результатам наблюдений излучения молекул 13CO и метанола. Впервые обнаружено увеличение ширин линий излучения молекулы 13CO с лучевыми скоростями около +90 и +105 км/с, что является новым свидетельством возможного взаимодействия ОСН Kes 79 с молекулярными облаками. Увеличение ширины линии с лучевой скоростью +105 км/с наблюдается по всей поверхности остатка. Для линии с лучевой скоростью +90 км/с увеличение ширины наблюдается в области северо-восточной границы остатка. В направлении на наблюдавшуюся ранее в Kes 79 область излучения молекулы ОН обнаружен источник мазерного излучения молекулы метанола. Предполагается, что он связан с результатом взаимодействия молекулярного облака, движущегося с лучевой скоростью +90 км/с, и ОСН. Интенсивность обнаруженного источника изменялась со временем.
