Galactic kinematics from data on open star clusters from the MWSC catalogue [PDF]

open access: yes, 2016
Open star clusters from the MWSC (Milky Way Star Clusters) catalogue have been used to determine the Galactic rotation parameters. The circular rotation velocity of the solar neighborhood around the Galactic center has been found from data on more than ...

Do open star clusters evolve towards energy equipartition [PDF]

open access: yes, 2016
We investigate whether open clusters (OCs) tend to energy equipartition, by means of direct N-body simulations with a broken power-law mass function. We nd that the simulated OCs become strongly mass segregated, but the local velocity dispersion does not

Massive open star clusters using the VVV survey - V. Young clusters with an OB stellar population [PDF]

open access: yes, 2016
The ESO public survey VISTA Variables in the Via Lactea (VVV) has contributed with deep multi-epoch photometry of the Galactic bulge and the adjacent part of the disk over 526 square degrees.

Massive White Dwarfs in Young Star Clusters [PDF]

open access: yesAstrophysical Journal, 2021
We have carried out a search for massive white dwarfs (WDs) in the direction of young open star clusters using the Gaia DR2 database. The aim of this survey was (1) to provide robust data for new and previously known high-mass WDs regarding cluster ...

Variable stars in open clusters [PDF]

open access: yesProceedings of the International Astronomical Union, 2013
AbstractWe present our joint efforts to study variable stars in open clusters. This includes a new catalogue, a photometric survey for new variables, and the database WEBDA. Our tools will shed more light on stellar variability in open clusters.

Binary Star Evolution in Different Environments: Filamentary, Fractal, Halo, and Tidal Tail Clusters

open access: yesThe Astronomical Journal, 2023
Using membership of 85 open clusters from previous studies based on Gaia Data Release 3 data, we identify binary candidates in the color–magnitude diagram for systems with mass ratio q > 0.4.

Roche volume filling and the dissolution of open star clusters [PDF]

open access: yes, 2015
From direct N-body simulations we find that the dynamical evolution of star clusters is strongly influenced by the Roche volume filling factor. We present a parameter study of the dissolution of open star clusters with different Roche volume filling ...

Three new Galactic star clusters discovered in the field of the open cluster NGC 5999 withGaia DR2 [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2018
We report the serendipitous discovery of three new open clusters, named UFMG 1, UFMG 2 and UFMG 3 in the field of the intermediate-age cluster NGC 5999, by using Gaia DR2 data.
