TLDR
In this article, the authors focus on characterizing the young stellar population in the Rosette complex to improve the understanding of the processes that regulate the star formation in this region and propose an original method that relies on the joint analysis of the star color and density in the near-infrared, leading to mapping the molecular cloud spatial distribution and detecting the embedded clusters with their characterization in terms of member number and age estimation.Abstract:
Aims. We focus on characterizing the young stellar population in the Rosette complex to improve our understanding of the processes that regulate the star formation in this region. Methods. We propose an original method that relies on the joint analysis of the star color and density in the near-infrared. It leads to mapping the molecular cloud spatial distribution and detecting the embedded clusters with their characterization in terms of member number and age estimation. Results. We have identified 13 clusters, 2 of which are new discoveries, and we estimate that the total number of young stellar objects in the Rosette ranges between 4000 and 8000 members. We find that the age distribution of the young clusters is not consistent with a general triggered scenario for the star formation in this molecular cloud. Conclusions. This study proves that the Rosette complex evolution is not governed by the influence of its OB star population. It suggests that the simple morphological appearance of an active region is not sufficient to conclude much about the triggering role in the star formation process. Our method of constraining the cluster properties using UKIDSS and WISE data has proven efficient, and studies of other regions of the Galactic plane would definitely benefit from this approach.read more

Understanding star formation in molecular clouds - I. Effects of line-of-sight contamination on the column density structure

TL;DR: In this paper, a first-order approximation of the column density probability distribution function (PDF) was applied to the column densities of a set of star-forming clouds, and the results showed that the PDF becomes broader, the peak shifts to lower column density and the power-law tail of the PDF flattens after correction.

The dangers of being trigger-happy
TL;DR: In this paper, the authors examined the evidence offered for triggered star formation against the backdrop provided by recent numerical simulations of feedback from massive stars at or below giant molecular cloud sizescales, and found that none of the observational markers improved the chances of correctly identifying a given star as triggered by more than factors of two at most.
