On the origin of the red excess in very young super star clusters: the case of SBS 0335-052E [PDF]

, 2010
The spectral energy distribution analysis of very young unresolved star clusters challenges our understanding of the cluster formation process. Studies of resolved massive clusters in the Milky Way and in the nearby Magellanic Clouds show us that the ...

Early dynamical evolution of star cluster systems [PDF]

, 2009
Violent relaxation -- the protocluster dynamical response to the expulsion of its residual star forming gas -- is a short albeit crucial episode in the evolution of star clusters and star cluster systems. Because it is heavily driven by cluster formation

Formation of Young Star Clusters [PDF]

Highlights of Astronomy, 2005
AbstractTurbulence, self-gravity, and cooling convert most of the interstellar medium into cloudy structures that form stars. Turbulence compresses the gas into clouds directly and it moves pre-existing clouds around passively when there are multiple phases of temperature.

Variability of young massive stars in the Arches cluster [PDF]

Proceedings of the International Astronomical Union, 2010
AbstractWe present preliminary results of the first near-infrared variability study of the Arches cluster, using adaptive optics data from NIRI/Gemini and NACO/VLT. The goal is to discover eclipsing binaries in this young (2.5 ± 0.5 Myr), dense, massive cluster for which we will determine accurate fundamental parameters with subsequent spectroscopy ...

Dynamics of black hole–neutron star binaries in young star clusters [PDF]

Monthly Notices of the Royal Astronomical Society, 2020
ABSTRACT Young star clusters are likely the most common birthplace of massive stars across cosmic time and influence the formation of compact binaries in several ways. Here, we simulate the formation of black hole–neutron star binaries (BHNSs) in young star clusters, by means of the binary population synthesis code MOBSE interfaced with ...

The Star Cluster System in the Local Group Starburst Galaxy IC 10

, 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.

Young Star Clusters in the LMC [PDF]

Australian Journal of Physics, 1992
The young globular star clusters in the LMC offer us insights into the formation and early dynamical evolution of globular clusters which are unobtainable from the old globular clusters in our Galaxy. Because these young clusters are so young and populous, they provide an opportunity to measure the upper end of the initial mass function by direct means

Age and mass studies for young star clusters in M31 from SEDs-fit

, 2012
In this paper, we present photometry for young star clusters in M31, which are selected from Caldwell et al. These star clusters have been observed as part of the Beijing--Arizona--Taiwan--Connecticut (BATC) Multicolor Sky Survey from 1995 February to ...

The embedded cluster or association Trumpler 37 in IC1396: a search for evolutionary constraints [PDF]

, 2012
It is currently widely accepted that open star clusters and stellar associations result from the evolution of embedded star clusters. Parameters such star formation efficiency, time-scale of gas removal and velocity dispersion can be determinants of ...

THE FORMATION AND DYNAMICAL EVOLUTION OF YOUNG STAR CLUSTERS

The Astrophysical Journal, 2016
ABSTRACT Recent observations have revealed a variety of young star clusters, including embedded systems, young massive clusters, and associations. We study the formation and dynamical evolution of these clusters using a combination of simulations and theoretical models.
