We analyze the masses and spatial distributions of fourteen young stellar groups in Taurus, Lupus3, ChaI, and IC348. These nearby groups, which typically contain 20 to 40 members, have membership catalogs complete to ~0.02 M_sun, and are sufficiently young that their locations should be similar to where they formed. These groups show five properties seen in clusters having many more stars and much greater surface density of stars: (1) a broad range of masses, (2) a concentration of the most… Expand
We analyze high-quality, complete stellar catalogs for four young (roughly 1 Myr) and nearby (within {approx}300 pc) star-forming regions: Taurus, Lupus3, ChaI, and IC348, which have been previouslyExpand
The formation and evolution of small star clusters
Recent observations show that small, young, stellar groupings of � 10 to 40 members tend of have a centrally-located most massive member, reminiscent of mass segregation seen in large clusteredExpand
Massive stars can be efficiently ejected from their birth star clusters through encounters with other massive stars. We study how the dynamical ejection fraction of O star systems varies with theExpand
The origin of discrete multiple stellar populations in globular clusters
Recent observations have revealed that at least several old globular clusters (GCs) in the Galaxy have discrete distributions of stars along the Mg-Al anti-correlation. In order to discuss thisExpand
Catalog of High Protostellar Surface Density Regions in Nearby Embedded Clusters
We analyze high-quality stellar catalogs for 24 young and nearby (within 1 kpc) embedded clusters and present a catalogue of 32 groups which have a high concentration of protostars. The medianExpand
Mass distributions of stars and cores in young groups and clusters
We investigate the relation of the stellar initial mass function (IMF) and the dense core mass function (CMF), using stellar masses and positions in 14 well-studied young groups. Initial columnExpand
Very massive stars in not so massive clusters
Very young star clusters in the Milky Way exhibit a well-defined relation between their maximum stellar mass, m_max, and their mass in stars, M_ecl. A recent study shows that the youngExpand
The Spatial Structure of Young Stellar Clusters. III. Physical Properties and Evolutionary States
We analyze the physical properties of stellar clusters that are detected in massive star-forming regions in the MYStIX project--a comparative, multiwavelength study of young stellar clusters withinExpand

Abstract Some ultra-compact dwarf galaxies have large dynamical mass to light (M / L) ratios and also appear to contain an overabundance of LMXB sources, and some Milky Way globular clusters have aExpand
The influence of stellar dynamical ejections and collisions on the relation between the maximum stellar and star cluster mass
We perform the largest currently available set of direct N-body calculations of young star cluster models to study the dynamical influence, especially through the ejections of the most massive starExpand


A Catalog of Young Stellar Groups and Clusters within 1 Kiloparsec of the Sun
We present a catalog of near-infrared surveys of young ( a few 106 yr) stellar groups and clusters within 1 kpc from the Sun, based on an extensive search of the literature from the past ten years.Expand
The stellar population of the Lupus clouds
We present photometric and spectroscopic observations of the H alpha emission stars in the Lupus dark cloud complex. We estimate the effective temperatures of the stars from their spectral types andExpand
The Disk Population of the Taurus Star-Forming Region
We have analyzed nearly all images of the Taurus star-forming region at 3.6, 4.5, 5.8, 8.0, and 24??m that were obtained during the cryogenic mission of the Spitzer Space Telescope (46 deg2) and haveExpand
The Formation of Massive Stars from Turbulent Cores
Observations indicate that massive stars in the Galaxy form in regions of very high surface density, � � 1 gc m � 2 . Clusters containing massive stars and globular clusters have a column densityExpand
Hierarchical Star Formation: Stars and Stellar Clusters in the Gould Belt
We perform a study of the spatial and kinematical distribution of young open clusters in the solar neighborhood, discerning between bound clusters and transient stellar condensations within ourExpand
Star formation in the Vela molecular clouds. V. Young stellar objects and star clusters towards the C-cloud
We present the latest results from a sensitive (K ∼ 18 mag) near-infrared (JHK) imaging survey of IRAS selected young stellar objects associated with the Vela molecular ridge. These enlarge theExpand
Filamentary structure of star-forming complexes
The nearest young stellar groups are associated with hubs of column density exceeding 1022 cm?2, according to recent observations. These hubs radiate multiple filaments of parsec length, having lowerExpand
The Stellar Population of the Chamaeleon I Star-Forming Region
I present a new census of the stellar population in the Chamaeleon I star-forming region. Using optical and near-IR photometry and follow-up spectroscopy, I have discovered 50 new members ofExpand
The simultaneous formation of massive stars and stellar clusters
We show that massive stars and stellar clusters are formed simultaneously, the global evolution of the forming cluster is what allows the central stars to become massive. We predict that massiveExpand
Modes of Multiple Star Formation
This paper argues that star-forming environments should be classified into finer divisions than the traditional isolated and clustered modes. Using the observed set of Galactic open clusters andExpand
