Origin of open clusters revealed by the evolution of the m_maxM_ecl relation
J. W. Zhou, Sami Dib, Pavel Kroupa
Using the Gaia DR3 open cluster catalog, we identified the most massive star in each observed cluster. Examining the m_maxM_cluster relations across different age ranges, we fin…
Connecting Star Formation in the Milky Way and Nearby Galaxies -II. An Observationally Driven Analytical Model for Predicting Cloud-Scale Star Formation Rates
J. W. Zhou, Amelie Saintonge, Sami Dib +1
We construct a model by integrating observational constraints from the Milky Way and nearby galaxies to predict cloud-scale star formation rates (SFRs). In the model, we first esti…
The post-gas expulsion coalescence of embedded clusters as an origin of open clusters
J. W. Zhou, Sami Dib, Pavel Kroupa
The mismatch between the mass function of the Milky Way's embedded clusters (ECs) and that of open clusters (OCs) raises the question of whether each OC originates from a single EC…
The star formation histories, star formation efficiencies and ionizing sources of ATLASGAL clumps with HII regions
J. W. Zhou, Sami Dib, Pavel Kroupa
1226 ATLASGAL clumps with HII regions were matched with radio sources in the CORNISH-North/South surveys, and 392 of them have corresponding radio sources. We determined the stella…
Physical properties of embedded clusters in ATLASGAL clumps with HII regions
J. W. Zhou, Pavel Kroupa, Sami Dib
Using the optimal sampling model, we synthesized the embedded clusters of ATLASGAL clumps with HII regions (HII-clumps). The 0.1 Myr isochrone was used to estimate the bolometric l…
Self-similar cluster structures in massive star-forming regions: Isolated evolution from clumps to embedded clusters
J. W. Zhou, Pavel Kroupa, Sami Dib
We used the dendrogram algorithm to decompose the surface density distributions of stars into hierarchical structures. These structures were tied to the multiscale structures of st…
