Validating Open Cluster Candidates with Photometric Bayesian Evidence
The Astrophysical JournalThe thousands of open cluster (OC) candidates identified by the Gaia mission are significantly contaminated by false positives from field star fluctuations, posing a major validation challenge.

Chemical analysis of giant stars in the young open cluster NGC 3114 [PDF]
, 2013 Context. Open clusters are very useful targets for examining possibl e trends in galactocentric distance and age, especially whe n young and old open clusters are compared. Aims.

Vilnius Multicolor CCD Photometry of the Open Cluster NGC 752
Open Astronomy, 2011 We have performed multicolor CCD observations of the central area of NGC 752 to search for faint, low-mass members of this open cluster. Four 12’ x 12’ fields were taken on the 1.8 m Vatican Advanced Technology Telescope (Mt.

NGC 6994: an open cluster which is not an open cluster
, 2000 We report on CCD photometry in the Johnson B,V and I passbands for 146 stars in a 9' \times 9' region around the southern aggregate NGC 6994 (C 2056-128), which appears in the Lynga (1987) catalogue of open star clusters. We argue that this object is not really an open cluster, but simply a random enhancement of four bright stars above the background ...

Open Clusters: Open Windows on Stellar Dynamics [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractThe extensive stellar radial-velocity surveys of the WIYN Open Cluster Study now allow comprehensive studies of the solar-type hard-binary populations in open clusters as a function of age. We first describe an empirical “initial” hard-binary population as derived from the young open cluster NGC 2168 (M35).
