Bipolar Molecular Motion of Matter in the Star Forming Region IRAS 22267+6244
The high-mass star-forming region IRAS 22267+6244 has been mapped in the J =1−0 line of 13CO at 110.2 GHz. We have found that the bipolar outflow which had been observed in the line of 12CO in this object, is also observed in the line of 13CO. This outflow is observed as the systematic shift of the...

V. Shulga, V. M. The high-mass star-forming region IRAS 22267+6244 has been mapped in the J =1−0 line of 13CO at 110.2 GHz. We have found that the bipolar outflow which had been observed in the line of 12CO in this object, is also observed in the line of 13CO. This outflow is observed as the systematic shift of the line profile accompanied by the change of the distance from the cloud centre. Bipolar outflow parameters have been calculated using the radiation of 13CO molecule. The bipolar outflow constitutes a significant part of the molecular cloud mass. The dependence of the average velocity of the bipolar outflow on distance from the central source appears to be linear. Comparison of the high-velocity (12CO) and low-velocity (13CO) parts of the bipolar outflow shows their similar morphology and comparable kinetic energy. Kinetic energy of the turbulent movement and binding energy of the molecular cloud has been calculated. They are shown to be comparable to the energy of the bipolar outflow. Проведено картографирование области звездообразования большой массы IRAS 22267+6244в линии молекулы <sup>13</sup>CO (J =1−0) на частоте 110.2 ГГц. Установлено, что биполярный поток,наблюдавшийся ранее в этом объекте в линиях молекулы <sup>12</sup>CO, наблюдается также в линии мо-лекулы <sup>13</sup>CO и проявляется в систематическом сдвиге профиля линии с изменением расстоянияот центра облака. По излучению молекулы <sup>13</sup>CO рассчитаны параметры биполярного потока.Показано, что биполярный поток составляет значительную часть массы молекулярного облака.Установлено, что скорость биполярного потока линейно увеличивается с расстоянием от централь-ного источника. Сравнение высокоскоростной (<sup>12</sup>CO) и низкоскоростной (<sup>13</sup>CO) частей биполярногопотока показало, что они имеют сходную морфологию и примерно одинаковую кинетическую энергию.Рассчитаны кинетическая энергия турбулентного движения и энергия связи молекулярного облакаи показано, что они сравнимы с энергией биполярного потока.

| description |
The high-mass star-forming region IRAS 22267+6244 has been mapped in the J =1−0 line of 13CO at 110.2 GHz. We have found that the bipolar outflow which had been observed in the line of 12CO in this object, is also observed in the line of 13CO. This outflow is observed as the systematic shift of the line profile accompanied by the change of the distance from the cloud centre. Bipolar outflow parameters have been calculated using the radiation of 13CO molecule. The bipolar outflow constitutes a significant part of the molecular cloud mass. The dependence of the average velocity of the bipolar outflow on distance from the central source appears to be linear. Comparison of the high-velocity (12CO) and low-velocity (13CO) parts of the bipolar outflow shows their similar morphology and comparable kinetic energy. Kinetic energy of the turbulent movement and binding energy of the molecular cloud has been calculated. They are shown to be comparable to the energy of the bipolar outflow. |
