The structure of young star clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 1999 We analyse and compare the clustering of young stars in Chamaeleon I and Taurus. We compute the mean surface-density of companion stars \bar{N} as a function of angular displacement from each star. We then fit \bar{N}( ) with two simultaneous power laws.

Formation of new stellar populations from gas accreted by massive young star clusters [PDF]
Nature, 2016 Stars in clusters are thought to form in a single burst from a common progenitor cloud of molecular gas. However, massive, old ‘globular’ clusters—those with ages greater than ten billion years and masses several hundred thousand times that of the Sun ...

Star Cluster Evolution: From Young Massive Star Clusters to Old Globulars [PDF]
, 2009 Young, massive star clusters are the most notable and significant end products of violent star-forming episodes triggered by galaxy collisions, mergers, and close encounters. The question remains, however, whether or not at least a fraction of the compact YMCs seen in abundance in extragalactic starbursts, are potentially the progenitors of globular ...

Dynamical ejections of massive stars from young star clusters under diverse initial conditions [PDF]
, 2016 We study the effects of initial conditions of star clusters and their massive star population on dynamical ejections of massive stars from star clusters up to an age of 3 Myr.

Young massive star clusters: achievements and challenges [PDF]
Proceedings of the International Astronomical Union, 2009 AbstractIn spite of significant recent and ongoing research efforts, most of the early evolution and long-term fate of young massive star clusters remain clouded in uncertainties. Here, I discuss our understanding of the initial conditions of star cluster formation and the importance of initial substructure for the subsequent dynamical-evolution and ...

The Astronomical Journal, 2023 Planets in young star clusters could shed light on planet formation and evolution since star clusters can provide accurate age estimation. However, the number of transiting planets detected in clusters was only ∼30, too small for statistical analysis ...

The R136 star cluster dissected with Hubble Space Telescope/STIS. I. Far-ultraviolet spectroscopic census and the origin of He II λ1640 in young star clusters [PDF]
, 2016 We introduce a Hubble Space Telescope (HST)/Space Telescope Imaging Spectrograph (STIS) stellar census of R136a, the central ionizing star cluster of 30 Doradus.

The Evolution of Substructure during Star Cluster Assembly
The Astrophysical JournalStar cluster formation and assembly occur inside filamentary and turbulent molecular clouds, which imprint both spatial and kinematic substructure on the young cluster.

Hierarchical black hole triples in young star clusters: impact of Kozai-Lidov resonance on mergers [PDF]
, 2016 Mergers of compact object binaries are one of the most powerful sources of gravitational waves (GWs) in the frequency range of second-generation ground-based gravitational wave detectors (Advanced LIGO and Virgo).

An In-depth Investigation of the Primordial Cluster Pair ASCC 19 and ASCC 21
The Astronomical JournalUtilizing Gaia data from the literature, we report a new young (∼8.9 Myr) cluster pair, ASCC 19 and ASCC 21, located near the Orion star-forming complex. The clusters are separated by a 3D distance of 27.00 ± 7.51 pc.
