2 Apr 2019 | | Abstract: | We present an observational study of small-scale feedback processes operating
in the star-forming region located in the wall of the expanding supershell
around the Cyg OB1 association. The interstellar gas and dust content and
pre-stellar populations in the vicinity of the open star cluster vdB 130 are
analysed based on new optical and IR observations performed with the 6-m (3D
spectroscopic mapping in the [SII] doublet) and 2.5-m (optical and NIR images)
Russian telescopes along with the archival data of Spitzer and Herschel space
telescopes. Analysing ionized gas kinematics and emission spectra, we
discovered a compact region with supersonic motions. These motions may be
caused either by stellar wind, or a bipolar outflow from a protostellar disc.
Young stellar objects were identified and classified in the area under study.
Two star-forming regions were identified. One of them is a region of ongoing
star formation in the head of the molecular cloud observed there and another
one is a burst of star formation in the cloud tail. | | Source: | arXiv, 1904.1641 | | Services: | Forum | Review | PDF | Favorites | |
