Watson P. Varricatt

TL;DR
This study reveals multiple outflows and star formation activity in the IRAS 07422-2001 region, highlighting early-stage YSOs, circumstellar disks, and hierarchical cluster formation through detailed infrared observations and radiative transfer modeling.
Contribution
It provides the first detailed analysis of multiple outflows and the evolutionary stages of YSOs in IRAS 07422-2001 using multi-wavelength data and radiative transfer models.
Findings
At least six outflows from the IRAS-associated cluster.
Detection of a tentative circumstellar disk in the IRAS cluster.
Evidence of hierarchical star formation and competitive accretion.
Abstract
The luminous Young Stellar Object (YSO) IRAS 07422-2001 is studied in the infrared. We discover star forming activity in embedded clusters located in a cloud detected at mid-IR wavelengths in emission. Multiple outflows are discovered from these clusters in the H_2 ro-vibrational line at 2.122 micron. We detect at least six outflows from the cluster associated with the IRAS source and another outflow from a source located in a cluster detected ~2.7 arcmin NE of the IRAS source. Additional star formation is taking place in two other cluster candidates within the cloud. Three of the YSOs in the cluster associated with the IRAS source are detected at 11.2 micron at an angular resolution of ~0.8 arcsec. We have a tentative detection of a circumstellar disk in this cluster, seen as an extinction lane in the J and H-band images. The spectral energy distributions (SEDs) of the dominant YSOs in…
