The occurrence of abnormal stars in open clusters [PDF]
The Astrophysical Journal, 1979 AbstractMorgan, Keenan, and others have found that low dispersions (80-130 Å mm-1) are ideal for obtaining spectral types and luminosity classes, especially for early-type stars. This is because at those dispersions certain blends are unresolved and remain useful, the hydrogen line wings are seen most clearly, and differences in rotational velocities ...

Automated search for galactic star clusters in large multiband surveys: I. Discovery of 15 new open clusters in the Galactic anticenter region [PDF]
, 2008 Aims: According to some estimations, there are as many as 100000 open clusters in the Galaxy, but less than 2000 of them have been discovered, measured, and cataloged. We plan to undertake data mining of multiwavelength surveys to find new star clusters.

Variable stars in open clusters [PDF]
Proceedings 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.

Star clusters in the Sh2-132 complex: clues about the connection between embedded and open clusters [PDF]
, 2010 Embedded clusters are formed in molecular clouds where massive stars can produce HII regions. The detailed embedded-open cluster evolutionary connection as well as the origin of associations are yet to be unveiled.

Stars with Abnormal Spectra in Open Clusters [PDF]
Symposium - International Astronomical Union, 1980 From the literature a list of stars with abnormal spectra belonging to open clusters was compiled. This list is included in Lyngå's catalogue of open clusters. With this data it becomes possible to derive a correlation with the age, compiled by W. Buscombe and which appears also in Lyngå's catalogue.

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.

NGC 4337: an over-looked old cluster in the inner disc of the Milky Way [PDF]
, 2014 Galactic open clusters do not survive long in the high density regions of the inner Galactic disc. Inside the solar ring only 11 open clusters are known with ages older than one Gyr.

Blue Straggler Stars in Galactic Open Clusters and the effect of field star contamination [PDF]
, 2008 We investigate the distribution of Blue Straggler stars in the field of three open star clusters. The main purpose is to highlight the crucial role played by general Galactic disk fore-/back-ground field stars, which are often located in the same region ...
