A catalog of newly identified star clusters in GAIA DR2 [PDF]
Astrophysical Journal Supplement Series, 2019 We present the Star cluster Hunting Pipeline (SHiP) which can identify star clusters in GAIA DR2 data, and establish a star cluster catalog for the Galactic disk. A Friend of Friend based cluster finder method is used to identify star clusters using 5-dimensional stellar parameters, $l, b, \varpi, \mu_\alpha\cos\delta$, and $\mu_\delta$.

, 1993 This review concentrates almost entirely on globular star clusters. It emphasises the increasing realisation that few of the traditional problems of star cluster astronomy can be studied in isolation: the influence of the Galaxy affects dynamical ...

Proceedings of the International Astronomical Union, 2009 The centers of most galaxies in the local universe are occupied by compact, barely resolved sources. Based on their structural properties, position in the fundamental plane, and integrated spectra, these sources clearly have a stellar origin.

The star cluster - field star connection in nearby spiral galaxies. II. Field star and cluster formation histories and their relation [PDF]
, 2011 Recent studies have started to cast doubt on the assumption that most stars are formed in clusters. Observational studies of field stars and star cluster systems in nearby galaxies can lead to better constraints on the fraction of stars forming in clusters.

The Star Cluster System in the Local Group Starburst Galaxy IC 10 [PDF]
, 2015 We present a survey of star clusters in the halo of IC 10, a starburst galaxy in the Local Group based on Subaru R band images and NOAO Local Group Survey UBVRI images. We find five new star clusters. All these star clusters are located far from the center of IC 10, while previously known star clusters are mostly in the main body.

Evolution of Star Clusters near the Galactic Center: Fully Self-consistent N-body Simulations [PDF]
, 2007 We have performed fully self-consistent $N$-body simulations of star clusters near the Galactic center (GC). Such simulations have not been performed because it is difficult to perform fast and accurate simulations of such systems using conventional methods.

Star Cluster Survival in Star Cluster Complexes under Extreme Residual Gas Expulsion [PDF]
, 2005 After the stars of a new, embedded star cluster have formed they blow the remaining gas out of the cluster. Especially winds of massive stars and definitely the on-set of the first supernovae can remove the residual gas from a cluster. This leads to a very violent mass-loss and leaves the cluster out of dynamical equilibrium.

The Star Clusters in the Irregular Galaxy NGC 4449 [PDF]
, 2000 We examine the star clusters in the irregular galaxy NGC 4449. We use a near-infrared spectrum and broad-band images taken with the HST to place a limit of 8--15 Myrs on the age of the bright central ojbect in NGC 4449. Its luminosity and size suggest that it is comparable to young super star clusters.

The star formation history of the Large Magellanic Cloud as seen by star clusters and stars [PDF]
, 2010 The aim of this work is to test to what extent the star cluster population of a galaxy can be utilised to constrain or estimate the star formation history, with the Large Magellanic Cloud as our testbed. We follow two methods to extract information about the star formation rate from star clusters, either using only the most massive clusters ...

Multiple Populations in Star Clusters
Universe, 2022 We review the multiple population (MP) phenomenon of globular clusters (GCs): i.e., the evidence that GCs typically host groups of stars with different elemental abundances and/or distinct sequences in photometric diagrams.
