Mass segregation and cluster properties

Abstract

The infrared dark cloud G14.225−0.506 hosts two protoclusters in its northern and southern hubs, making it an ideal target for investigating clustering and mass segregation in early stages of cluster formation. By analyzing multi-wavelength data from millimeter, centimeter, and infrared catalogs, we constructed Minimum Spanning Trees (MSTs) to study the spatial distribution of young stellar popullation. Key statistical parameters, such as the Q parameter and the mass segregation ratio (ΛMSR), were calculated to assess whether the clusters exhibit fractal or centrally concentrated structures. Our findings reveal subclustering in some of the sources and peak centering in others and a notable mass segregation in the northern hub, while the southern hub displays a more uniform distribution. These results enhance our understanding of the physical conditions, dynamics, and evolution of protoclusters
