| Abstract: Jets/outflows are ubiquitous tracers of active star formation. The outflows are primarily driven by YSOs in the early stages of stellar evolution. While various studies discuss the role played by magnetic fields in star formation and its alignment with outflow orientation, both preferred and random alignment of magnetic fields compared to orientation of outflows and filamentary structures in molecular clouds have been observed. In this work, we present the analysis of a large sample of jet-bearing YSOs identified towards the Cygnus-X region spanning 42 sq. deg. by Makin et. al. 2018. Using IR observations from the 2MASS and WISE survey, we fitted the spectral energy distributions to radiative transfer models in order to estimate the mass and luminosity of the driving sources of the outflows. We find that the outflows in the region are predominantly driven by intermediate mass Class 0/1 YSOs. The physical parameters of outflows such as outflow length and luminosity are found to be correlated with physical parameters of driving source. The observed correlations corroborates with the findings of similar research done using the UWISH2 survey. Additionally, we determine the magnetic field strength and orientation for the full study region using Planck polarisation observations. We observe that the magnetic field near the outflows are randomly oriented and no correlation is observed between position angles of the outflows and the orientation of the large scale magnetic field as observed by Planck. Finally, we discuss the alignment of magnetic fields with the structures observed in the Cygnus-X cloud complex. |
