Isolated massive star candidates in NGC 4242 with the Galaxy UV Legacy Project

Astronomy & Astrophysics
Context. There is considerable debate about the formation of massive stars, including whether a high-mass star must always form with a population of low-mass stars, or if it can also form in isolation.

The X-Ray Binary-star Cluster Connection in Late-type Galaxies

The Astrophysical Journal, 2023
We conduct one of the largest systematic investigations of bright X-ray binaries (XRBs) in both young star clusters and ancient globular clusters (GCs) using a sample of six nearby star-forming galaxies.

Hidden Gems on a Ring: Infant Massive Clusters and Their Formation Timeline Unveiled by ALMA, HST, and JWST in NGC 3351 [PDF]

Astrophysical Journal
We use 0.1″ observations from the Atacama Large Millimeter Array (ALMA), Hubble Space Telescope (HST), and JWST to study young massive clusters (YMCs) in their embedded “infant” phase across the central starburst ring in NGC 3351.

Very Massive Stars and High N/O: A Tale of the Nitrogen-enriched Super Star Cluster in the Sunburst Arc

The Astrophysical Journal
The lensed Sunburst Arc ( z = 2.369) hosts a young (∼2–4 Myr), massive ( M _⋆  ∼ 10 ^7 M _⊙ ), compact ( R _eff  ∼ 8 pc) Lyman-continuum leaking super star cluster, which powers a compact (

Effective Radii of Young, Massive Star Clusters in Two LEGUS Galaxies [PDF]

, 2017
We present a study of the effective (half-light) radii and other structural properties of a systematically selected sample of young, massive star clusters (≥5 × 103 and ≤200 Myr) in two nearby spiral galaxies, NGC 628 and NGC 1313.

Formation of young massive clusters from turbulent molecular clouds [PDF]

, 2014
Young massive clusters are as young as open clusters but more massive and compact compared with typical open clusters. The formation process of young massive clusters is still unclear, and it is an open question whether the formation process is the same ...

The Close Binary Properties of Massive Stars across Different Environments within the LMC

The Astrophysical Journal
We analyze 4859 O stars in the third phase of the Optical Gravitational Lensing Experiment photometric survey of the LMC, including 415 eclipsing binaries (EBs).

Properties of massive stars in four clusters of the VVV survey

, 2015
The evolution of massive stars is only partly understood. Observational constraints can be obtained from the study of massive stars located in young massive clusters.

Young Massive Clusters – Formation Efficiencies and (Initial) Mass Functions [PDF]

, 2008
Globular clusters are often assumed to be good tracers of major star formation episodes in their host galaxies. While observations over the past 2 decades have confirmed the presence of young objects with globular cluster-like properties in many galaxies, it is still not well understood exactly how the formation efficiency of bound star clusters ...
