| Abstract : | Stars form within dense gas clumps that provide ideal conditions for probing how the stars are born and how they evolve in the earliest stages via young stellar objects (YSOs) and embedded pre-main sequence stars. It has been found that the isolated formation of a star is rare and that they form in clusters. The molecular cloud Monoceros OB1 is a star-forming region located at around 720 pc from the sun towards the Galactic anti-center direction. It consists of NGC 2264 and a reflection nebula on the west termed Mon R1. To understand the complete census of the stellar population in this region and the current state of star formation we have utilized the latest Gaia data release 3 (DR3). We have applied density-based clustering algorithms to a sample obtained from the Gaia catalog for a circular region of radius of 3.5 degrees in 5-dimensional space comprising of the spatial location and proper motion in the sky as well as the distance.
We identified two clusters out of which one belongs to NGC 2264, and the second belongs to Mon R1 located at a distance of 700pc. Combining the Gaia DR3 data with 2MASS and WISE photometry we identified Class I and Class II YSOs in these regions. Furthermore, we have identified two distinct proper motions within NGC 2264 suggesting the sub-clustering within this region. |
