大质量恒星形成区G240.31+0.07的外向流研究

摘要：

outflows in star-forming region Ubiquitous,associated with Young Stellar Objects(YSOs) in star-forming regions.Dissipating excess an gular momentum.Origin:” Primary outflow: materials (jet or wind) ejected by central objects.” Secondary outflow: ambient gas swept up by jet or wind.Tracers:CO, SiO, H2 ...The driven mechanism of outflow is unknown.C0 2-1, 3-2, 6-5, 7-6 observations.LVG analysis and rotation diagram anaysis.lsothermal massive outflow.Agree with the low-mass wind-driven model.Decreasing Nco and probably decreasing n(H2) with velocity.Agree with the low-mass wind-driven model.Outlook: multi-line outflow survey.
