Catalogue of blue stragglers in open clusters Ahumada J., Lapasset E. <Astron. Astrophys. Suppl. Ser. 109, 375 (1995)> =1995A&AS..109..375A (SIMBAD/NED Reference)
ADC_Keywords: Clusters, open; Stars, blue ; Stars, peculiar Keywords: catalogues - open clusters and associations: general - stars: blue stragglers Description: An amount of 959 blue straggler candidates were selected from their position in the colour-magnitude diagram in 390 open clusters of all ages. A set of basic data is given for every cluster and blue straggler. File Summary:
