Description

We have created a catalog of significant small- scale structure of young stellar objects in star-forming regions and complexes within the Milky Way, which may correspond to pristine imprints of star formation and cloud fragmentation (Joncour+17, 18). The method of retrieval has been proven to give robust and consistent results in a variety of conditions (González+2021), and the regions were chosen from the MYStIX (Feigelson+13) and SFiNCs (Getman+17) surveys, observational programs specifically designed to compare star-forming regions and complexes of different sizes in the fairest way possible.

Our catalog allows to objectively separate modes of stellar formation within regions and evaluate the coupling of the clustered prestellar population with the gas distribution, revealing the diversity and intricacy of star formation within our galaxy.
