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 ...

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.

Universal Upper End of the Stellar Initial Mass Function in the Young and Compact LEGUS Clusters

The Astrophysical Journal, 2023
We investigate the variation in the upper end of the stellar initial mass function (uIMF) in 375 young and compact star clusters in five nearby galaxies within ∼5 Mpc. All the young stellar clusters (YSCs) in the sample have ages ≲ 4 Myr and masses above

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 ...

TESS Hunt for Young and Maturing Exoplanets (THYME). VII. Membership, Rotation, and Lithium in the Young Cluster Group-X and a New Young Exoplanet

The Astronomical Journal, 2022
The public, all-sky surveys Gaia and TESS provide the ability to identify new young associations and determine their ages. These associations enable study of planetary evolution by providing new opportunities to discover young exoplanets.

Be stars in and around young clusters in the Magellanic Clouds [PDF]

Astronomy and Astrophysics Supplement Series, 1999
We present the results of a search for Be stars in six fields centered on the young clusters NGC 330 and NGC 346 in the SMC, and NGC 1818, NGC 1948, NGC 2004 and NGC 2100 in the LMC. Be stars were identified by differencing R band and narrow-band H$α$ CCD images.

The young Galactic star cluster [DBS2003] 179 [PDF]

Astronomy & Astrophysics, 2008
Recent near- and mid-infrared surveys have brought evidence that the Milky Way continues to form massive clusters. We carry out a program to determine the basic physical properties of the new massive cluster candidate [DBS2003]179. Medium-resolution K-band spectra and deep near-infrared images of [DBS2003]179 were used to derive the spectral types of ...

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.
