Testing circumstellar disk lifetimes in young embedded clusters associated with the Vela Molecular Ridge [PDF]

open access: yes, 2010
Context. The Vela Molecular Ridge hosts a number of young embedded star clusters in the same evolutionary stage. Aims. The main aim of the present work is testing whether the fraction of members with a circumstellar disk in a sample of clusters in the ...

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

open access: yesAstronomy & 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 ...

The Star Clusters in the Irregular Galaxy NGC 4449 [PDF]

open access: yes, 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.

THE EVOLUTIONARY TRACKS OF YOUNG MASSIVE STAR CLUSTERS [PDF]

open access: yesThe Astrophysical Journal, 2014
Stars mostly form in groups consisting of a few dozen to several ten thousand members. For 30 years, theoretical models provide a basic concept of how such star clusters form and develop: they originate from the gas and dust of collapsing molecular clouds.

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

open access: yesThe 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.

Imaging of star clusters in unperturbed spiral galaxies with the Advanced Camera for Surveys. I. The low luminosity galaxy NGC 45 [PDF]

open access: yes, 2006
We present results from ACS and WFPC observations in the low luminosity galaxy NGC 45. We identified 28 young star cluster candidates. While the exact values of age, mass, and extinction depend somewhat on the choice of SSP models, we find no young ...

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

open access: yesThe 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
