Star clusters stand at the intersection of much of modern astrophysics: the ISM, gravitational
dynamics, stellar evolution, and cosmology. Here, we review observations and theoretical …

Young massive clusters (YMCs) are dense aggregates of young stars that form the
fundamental building blocks of galaxies. Several examples exist in the Milky Way Galaxy …

We analyse the first giant molecular cloud (GMC) simulation to follow the formation of
individual stars and their feedback from jets, radiation, winds, and supernovae, using the …

The Gaia mission has opened a new window into the internal kinematics of young star
clusters at the sub-km s− 1 level, with implications for our understanding of how star clusters …

We present an analysis of spectroscopic and astrometric data from APOGEE-2 and Gaia
DR2 to identify structures toward the Orion Complex. By applying a hierarchical clustering …

▪ Abstract Stellar clusters are born embedded within giant molecular clouds (GMCs) and
during their formation and early evolution are often only visible at infrared wavelengths …

Context. The distribution of member stars in the surroundings of an open cluster (OC) can
shed light on the process of its formation, evolution, and dissolution. The analysis of …

Theoretical modeling of massive stars predicts a gap in the black hole (BH) mass function
above∼ 40–50 M⊙ for BHs formed through single star evolution, arising from (pulsational) …

We review current understanding of star formation, outlining an overall theoretical framework
and the observations that motivate it. A conception of star formation has emerged in which …

Understanding the formation of stars in galaxies is central to much of modern astrophysics.
However, a quantitative prediction of the star formation rate and the initial distribution of …
