Evidence for Inflow in High-Mass Star-Forming Clumps
Evidence for Inflow in High-Mass Star-Forming Clumps
2011/10/17
We analyze the HCO+ 3-2 and H13CO+ 3-2 line profiles of 27 high-mass star-forming regions to identify asymmetries that are suggestive of mass inflow. Three quantitative measures of line asymmetry are ...
Outflow activities in the young high-mass stellar object G23.44-0.18
stars: pre-main sequence—ISM:molecules—ISM: individual (G23.44-0.18)—stars: formation
2011/9/29
We present an observational study towards the young high-mass star forming region G23.44-0.18 using the Submillimeter Array. Two massive, radio-quiet dusty cores MM1 and MM2 are observed in 1.3 mm con...
OH Masers and the Dust Emissions Towards High Mass Protostellar Objects

Context: OH maser emission is known to be associated with high mass star forming regions. Towards some of these regions, OH masers are associated with HII regions. Towards others, believed to be in an...
Dissecting high-mass star-forming regions; tracing back their complex formation history
high-mass star-forming regions tracing complex formation

We present near-infrared JHKs imaging as well as K-band multi-object spectroscopy of the massive stellar content of W3 Main using LUCI at the LBT. We confirm 13 OB stars by their absorption line spect...
