| 英文摘要 | An unbiased search of molecular outflows within the region of the CO High Resolution survey has identified 157 high-mass outflows from a sample of 770 APEX Telescope Large Area Survey of the Galaxy clumps with a detection rate of 20%. The detection rate of outflows increases for clumps with higher M-clump, L-bol, L-bol/M-clump, N-H2, and T-dust compared to the clumps with no outflow. The detection rates of the outflow increase from protostellar (8%) to young stellar object clump (17%) to massive star-forming clump (29%). The detection rate 26% for quiescent clump is preliminary, because the sample of quiescent clumps is small. A statistical relation between the outflow and clump masses for our sample is log(M-out/M-circle dot) = (-1.1 +/- 0.21) + (0.9 +/- 0.07) log(M-clump/M-circle dot). The detection rate of outflows and the outflow mass-loss rate show an increase with increasing M-clump,M- L-bol, N-H2, and T-dust, which indicates that clumps with outflow with higher parameter values are at a more advanced evolutionary stage. The outflow mechanical force increases with increasing bolometric luminosities. No clear evidence has yet been found that highermass outflows have different launching conditions than low-mass outflows. |
