Early turbulent mixing as the origin of chemical homogeneity in open star clusters [PDF]
Nature, 2014 The abundances of elements in stars are critical clues to stars’ origins. Observed star-to-star variations in logarithmic abundance within an open star cluster—a gravitationally bound ensemble of stars in the Galactic plane—are typically only about 0.01 ...

Compact Binary Formation in Open Star Clusters I: High Formation Efficiency of Gaia BHs and Their Multiplicities [PDF]
Monthly notices of the Royal Astronomical Society, 2023 Gaia BHs, black hole (BH) binaries discovered from database of an astrometric telescope Gaia, pose a question to the standard binary evolution model.

On the assessment of the nature of open star clusters and the determination of their basic parameters with limited data [PDF]
Astrophysics and Space Science, 2017 Our knowledge of stellar evolution and of the structure and chemical evolution of the Galactic disk largely builds on the study of open star clusters. Because of their crucial role in these relevant topics, large homogeneous catalogues of open cluster ...

Open star clusters and Galactic structure [PDF]
Proceedings of the International Astronomical Union, 2017 In order to understand the Galactic structure, we perform a statistical analysis of the distribution of various cluster parameters based on an almost complete sample of Galactic open clusters yet available. The geometrical and physical characteristics of

Tidal tails of open star clusters as probes of early gas expulsion [PDF]
Astronomy & Astrophysics, 2020 Context. Star clusters form in the densest parts of infrared dark clouds. The emergence of massive stars expels the residual gas that has not formed stars yet.

Global survey of star clusters in the Milky Way - III. 139 new open clusters at high Galactic latitudes [PDF]
, 2014 Context. An earlier analysis of the Milky Way Star Cluster (MWSC) catalogue revealed an apparent lack of old (t & 1 Gyr) open clusters in the solar neighbourhood (d. 1 kpc). Aims.

Open Star Clusters and Their Asymmetrical Tidal Tails [PDF]
The Astrophysical JournalStars that evaporate from their star cluster by the energy equipartition process end up in either a leading or a trailing tidal tail. In Newtonian gravitation and for open star clusters in the solar vicinity, the tidal threshold, or práh, for escape is ...

A CATALOG OF 120 NGC OPEN STAR CLUSTERS [PDF]
, 2011 A sample of 145 JHK{2MASS observations of NGC open star clusters is studied, of which 132 have never been studied before. Twelve are classifled as non-open clusters and 13 are re-estimated self-consistently, after applying the same methods in order to ...
