Hierarchical star formation
Web11 de nov. de 2024 · It is widely accepted that hierarchical fragmentation takes place in the star formation process on multiple scales, from molecular cloud to clump, and down to core scales. As shown in Fig. 1 , the G34 cloud does present a hierarchical fragmentation scenario with the intermediate-scale clumps fragmented from the large-scale filamentary … Webstar formation (Wang et al. 2006). With a typical star formation efficiency, the large amount of dense gas in these IRDCs makes them the natural birth place for massive stars and clusters. Thus, these regions are premium sites for uncovering the initial conditions of massive star and cluster formation.

Webmodes: ‘clustered’ and ‘ eld’ or ‘distributed’ star formation (Lada & Lada2003). However,Bressert et al.(2010) found that young stellar systems exist in a continuous range of stel-lar densities or masses, implying that there is no bimodality in star formation and star clusters only represent the densest part of the continuum. Web21 de jul. de 2009 · If we interpret this result in terms of a hierarchical star formation process (Elmegreen 2006, 2008), and considering that the age of the stars in both associations present similar ranges, we should consider either that the density maximum …
