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…
Early Stages of Protostellar Disk Evolution: A Link to the Initial Cloud Core
Majd Noel, Rahul Khanna, Shahram Abbassi +2
We study the structure and evolution of the very early protostellar disk (``protodisk'') just after protostar formation, where disk self-gravity dominates and the stellar contribut…
Connecting Star Formation in the Milky Way and Nearby Galaxies. I. Comparability of Molecular Cloud Physical Properties
J. W. Zhou, Sami Dib
We used CO (2-1) and CO (1-0) data cubes to identify molecular clouds and study their kinematics and dynamics in three nearby galaxies and the inner Milky Way. When observed at sim…
Inversely synthesizing the core mass function of high-mass star-forming regions from the canonical initial mass function
J. W. Zhou, Pavel Kroupa, Sami Dib
Many studies have revealed that the core mass function (CMF) in high-mass star-forming regions is top-heavy. In this work, we start from the canonical initial mass function (IMF) t…
An examination of large-scale galactic effects on molecular cloud properties in NGC 628 : The significant impact of tidal effects from neighboring material on the evolution of molecular clouds
J. W. Zhou, Sami Dib
The physical factors that influence the development of molecular cloud's density contrast are connected to those that affect star formation in the galaxy. For NGC 628 (M74), the pr…
