Nuclear star clusters [PDF]

Proceedings of the International Astronomical Union, 2009
AbstractThe centers of most galaxies in the local Universe are occupied by compact, barely resolved sources. Based on their structural properties, position in the Fundamental Plane, and integrated spectra, these sources clearly have a stellar origin. They are therefore called ‘nuclear star clusters’ (NCs) or ‘stellar nuclei’.

Modes of Multiple Star Formation [PDF]

, 2001
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 and theoretical considerations regarding cluster formation, we ...

Planetary systems in star clusters [PDF]

Proceedings of the International Astronomical Union, 2014
AbstractIn the solar neighborhood, where the typical relaxation timescale is larger than the cosmic age, at least 10% to 15% of Sun-like stars have planetary systems with Jupiter-mass planets. In contrast, dense star clusters, characterized by frequent close encounters, have been found to host very few planets.

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

The 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.

Star Formation in the Field and Clusters of NGC 5253 [PDF]

, 2001
We investigate the star formation history of both the bright star clusters and the diffuse `field star' population in the dwarf starburst galaxy NGC 5253 using STIS longslit ultraviolet spectroscopy.

Star cluster formation in Orion A [PDF]

Publications of the Astronomical Society of Japan, 2020
Abstract We introduce new analysis methods for studying the star cluster formation processes in Orion A, especially examining the scenario of a cloud–cloud collision. We utilize the CARMA–NRO Orion survey 13CO (1–0) data to compare molecular gas to the properties of young stellar objects from the SDSS III IN-SYNC survey. We show that the

Searching for New Globular Clusters in M31 with Gaia EDR3

The Astrophysical Journal, 2023
We have found 50 new globular cluster (GC) candidates around M31 with Gaia Early Data Release 3 (EDR3), with the help of Pan-STARRS1 DR1 magnitudes and Pan-Andromeda Archaeological Survey (PAndAS) images.

The Star Cluster System in the Local Group Starburst Galaxy IC 10

, 2015
We present a survey of star clusters in the halo of IC 10, a starburst galaxy in the Local Group based on Subaru R band images and NOAO Local Group Survey UBVRI images. We find five new star clusters.
