Massive star and star cluster formation [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractI review the status of massive star formation theories: accretion from collapsing, massive, turbulent cores; competitive accretion; and stellar collisions. I conclude the observational and theoretical evidence favors the first of these models.

Membership Analysis and 3D Kinematics of the Star-forming Complex around Trumpler 37 Using Gaia-DR3
The Astrophysical Journal, 2023 Identifying and characterizing young populations of star-forming regions are crucial to unraveling their properties. In this regard, Gaia-DR3 data and machine-learning tools are very useful for studying large star-forming complexes.

Odessa Astronomical Publications, 2017 Analysis of the absolute uvby photometry of the Open Clusters NGC 6910 and NGC 6913 show well-defined peaks that clearly define the accumulation of stars. Differential photometry of five stars in the direction of each cluster determines that at least two

The Astrophysical Journal Letters, 2023 We combine JWST/NIRCam imaging and MUSE data to characterize the properties of galaxies in different environmental conditions in the cluster Abell2744 ( z = 0.3064) and in its immediate surroundings. We investigate how galaxy colors, morphology, and star-

Star Cluster Survival in Star Cluster Complexes under Extreme Residual Gas Expulsion
, 2005 After the stars of a new, embedded star cluster have formed they blow the remaining gas out of the cluster. Especially winds of massive stars and definitely the on-set of the first supernovae can remove the residual gas from a cluster.

The Astrophysical Journal Supplement Series, 2023 Despite having data for over 10 ^9 stars from Gaia, less than 10 ^4 star clusters and candidates have been discovered. In particular, distant star clusters are rarely identified, due to the challenges posed by heavy extinction and great distance. However,

Calibration of radii and masses of open clusters with a simulation
, 2010 Context: A recent new approach to apply a simple dynamical mass estimate of tidally limited star clusters is based on the identification of the tidal radius in a King profile with the dynamical Jacobi radius.

The evolution of star clusters: the resolved-star approach
Astrophysics and Space Science, 2009 We present the first results of a new technique to detect, locate, and characterize young dissolving star clusters. Using HST/ACS archival images of the nearby galaxy IC2574, we performed stellar PSF photometry and selected the most massive stars as our first test sample.

Cluster and Double Star observations of dipolarization [PDF]
Annales Geophysicae, 2005 We studied two types of dipolarization events with different IMF conditions when Cluster and Double Star (TC-1) were located in the same local time sector: 7 August 2004, 18:00-24:00 UT, during a disturbed southward/northward IMF interval, and 14
