Young Massive Star Clusters [PDF]

Annual Review of Astronomy and Astrophysics, 2010
Young massive clusters (YMCs) are dense aggregates of young stars that form the fundamental building blocks of galaxies. Several examples exist in the Milky Way Galaxy and the Local Group, but they are particularly abundant in starburst and interacting galaxies.

Young Star Clusters in M 31 [PDF]

, 2008
In our study of M31's globular cluster system with MMT/Hectospec, we have obtained high-quality spectra of 85 clusters with ages less than 1 Gyr. With the exception of Hubble V, the young cluster in NGC 205, we find that these young clusters have kinematics and spatial distribution consistent with membership in M31's young disk.

Young Star Clusters: Progenitors of Globular Clusters!? [PDF]

Highlights of Astronomy, 2005
AbstractStar cluster formation is a major mode of star formation in the extreme conditions of interacting galaxies and violent starbursts. Young clusters are observed to form in a variety of such galaxies, a substantial number resembling the progenitors of globular clusters in mass and size, but with significantly enhanced metallicity.

Young Star Clusters in the LMC [PDF]

Symposium - International Astronomical Union, 1991
We discuss the integrated colours, kinematics, formation, dynamical evolution and initial mass functions of the young globular star clusters in the Large Magellanic Cloud (LMC). Because these clusters are so young, they offer us insights, unobtainable from the old globular clusters in our Galaxy, into the formation and early dynamical evolution of ...

Be Stars in Young LMC Clusters [PDF]

Symposium - International Astronomical Union, 1994
Slitless field Hα spectroscopy with a resolution of 0.2 nm has detected numerous Be stars in 3 young open star clusters in the LMC but only a few each in one Galactic and one LMC cluster. The line widths indicate rapid rotation as is typical of Galactic field Be stars.

Multi-Color Observations of Young Star Clusters [PDF]

Highlights of Astronomy, 2005
AbstractWe present a new set of evolutionary synthesis models of our GALEV code, specifically developed to include the gaseous emission of presently forming star clusters, in combination with an advanced tool to compare large model grids with multi-color broad-band observations of YSC systems. Tests and first applications are presented.

Star formation in young star cluster NGC 1893 [PDF]

Monthly Notices of the Royal Astronomical Society, 2007
We present a comprehensive multi-wavelength study of the star-forming region NGC 1893 to explore the effects of massive stars on low-mass star formation. Using near-infrared colours, slitless spectroscopy and narrow-band $H $ photometry in the cluster region we have identified candidate young stellar objects (YSOs) distributed in a pattern from the ...

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 ...
