207 New Open Star Clusters within 1 kpc from Gaia Data Release 2.

, 2019
We conducted a survey of open clusters within 1 kpc from the Sun using the astrometric and photometric data of the Gaia Data Release 2. We found 655 cluster candidates by visual inspection of the stellar distributions in proper motion space and spatial ...

Characteristics of the open star cluster Kronberger 60 using Gaia DR2

, 2020
The estimation of the main parameters of star clusters is a very important target in astrophysical studies. Many of the open clusters listed in known catalogs have insufficient astrometric parameters.

Be Stars in Open Stellar Clusters

Astrophysics, 2017
The current status of the problem of anomalous increases in the relative number of Be stars in young open stellar clusters is summarized in this article. The relative content of Be stars is shown to increase with the age of the clusters and reaches a maximum for stars in spectral classes B0-B3 when the age of the clusters is 12-20 Myr. In some clusters

The Kinematics and Velocity Ellipsoid Parameters of Open Star Clusters

, 2013
In terms of the equatorial coordinates, the galactic space velocity components were expressed in closed analyti- cal forms. With the aid of the vectors and matrices analyses expressions for the velocity ellipsoid parameters VEPs in closed analytical ...

Simulating Open Star Clusters

2001
We study the evolution of relatively young Galactic open clusters, such as the Pleiades, Praesepe and the Hyades. The calculations include a realistic mass function, primordial binaries and the external potential of the parent Galaxy. The equations of motions of all stars are computed using the GRAPE-4 while taking the evolution of single stars and ...

Populations of Variable Stars in Open Clusters

2011
We present our work in progress that explores links between properties of variable star populations and their host open clusters. Information from WEBDA and the Dias catalog [2] has been considered. We explain the context, consider open cluster red giants as tracers of a Galactic age-metallicity relationship, and outline the intended future direction ...
