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 â?¤ 1 Gyr) open clusters in the solar neighbourhood (d â?¥ 1 kpc). Aims.

Ultracool dwarfs in open clusters and star-forming regions [PDF]
EPJ Web of Conferences, 2013 In this contribution I review the results of the UKIRT Infrared Deep Sky Survey (UKIDSS) Galactic Clusters Survey (GCS) on the Initial Mass Function (IMF) and the current searches for young T dwarfs in open clusters and star-forming regions.

The Astrophysical Journal Supplement Series, 2023 Studying open clusters (OCs) may help to provide a comprehensive understanding of the structure and evolution of the Milky Way. Many previous studies have systematically searched for OCs near the solar system within 1.2 kpc or 20° of Galactic latitude ...

Unveiling Hidden Stellar Aggregates in the Milky Way: 1656 New Star Clusters Found in Gaia EDR3
The Astrophysical Journal Supplement Series, 2022 We report 1656 new star clusters found in the Galactic disk (∣ b ∣ < 20°) beyond 1.2 kpc, using Gaia EDR3 data. Based on an unsupervised machine-learning algorithm, DBSCAN, and following our previous studies, we utilized a unique method to do the data ...

An Investigation of Open Clusters Berkeley 68 and Stock 20 Using CCD UBV and Gaia DR3 Data
The Astronomical Journal, 2023 We performed detailed photometric and astrometric analyses of the open star clusters Berkeley 68 and Stock 20. This was based on ground-based CCD UBV photometric data complemented by space-based Gaia Data Release 3 (DR3) photometry and astrometry.

The Role of Binarity and Stellar Rotation in the Split Main Sequence of NGC 2422
The Astrophysical Journal, 2022 In addition to the extended main-sequence turnoffs widely found in young and intermediate-age (∼600 Myr to 2 Gyr old) star clusters, some younger clusters even exhibit split main sequences (MSs).

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 ...
