Radii of young star clusters in nearby galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT We measure the projected half-light radii of young star clusters in 31 galaxies from the Legacy Extragalactic UV Survey (LEGUS). We implement a custom pipeline specifically designed to be robust against contamination, which allows us to measure radii for 6097 clusters.

Young and intermediate-age massive star clusters [PDF]
Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2010 An overview of our current understanding of the formation and evolution of star clusters is given, with the main emphasis on high-mass clusters. Clusters form deeply embedded within dense clouds of molecular gas. Left-over gas is cleared within a few million years and, depending on the efficiency of star formation, the clusters may disperse almost ...

The initial properties of young star clusters in M83 [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT The initial sizes and masses of massive star clusters provide information about the cluster formation process and also determine how cluster populations are modified and destroyed, which have implications for using clusters as tracers of galaxy assembly.

Be stars in young clusters in the Magellanic Clouds
Space Science Reviews, 1993A substantial fraction (typically 10%) of Galactic B stars consists of Be stars. While Galactic Be stars have been fairly well investigated, very little is known about the Be star content of the Magellanic Clouds (MCs). We present a refined method of Be star identification by CCD photometry and apply it to four young clusters and associations in the ...

The bound fraction of young star clusters [PDF]
Astronomy and Astrophysics, 2017 The residual gas within newly formed star clusters is expelled through stellar feedback on timescales ~ 1 Myr. The subsequent expansion of the cluster results in an unbinding of a fraction of stars before the remaining cluster members can re-virialize and form a surviving cluster.

Relative content of Be stars in young open star clusters
Astronomy Letters, 2012Based on high- and medium-resolution spectra, we analyze the population of Be stars in eight young open star clusters. We have found a clear dependence of the relative content of early-type (B0-B3) Be stars on the cluster age. The relative concentration of Be stars of spectral types B0–B3 gradually increases with cluster age, reaching its maximum value
