cds-question@unistra.fropen-star-clustersmultiple-starsvariable-starsTwo hundred forty-two members of the Praesepe and alpha Persei clusters have been surveyed with high angular resolution 2.2{mu}m speckle imaging on the 3m Infrared Telescope Facility, the 5m Hale, and the 10m Keck telescopes, along with direct imaging using the near-infrared camera (NICMOS) aboard the Hubble Space Telescope. The observed stars range in spectral type from B (~5M_{sun}_) to early M (~0.5M_{sun}_), with the majority of the targets more massive than ~0.8M_{sun}_. The one quadruple and 39 binary systems detected encompass separations from 0.053" to 7.28"; 28 of the systems are new detections, and there are nine candidate substellar companions.2002AJ....123.1570Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/123/1570CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/257 : Proper Motions in Praesepe (Wang+, 1995)I/68 : Positions & Proper Motions in alpha Per (Fresneau, 1980)III/55 : Radial Velocities in Open Clusters (Mermilliod 1979)J/A+A/354/881 : Radial velocities of Praesepe + Hyades Am starsJ/A+A/375/989 : JHK photometry of Praesepe low-mass stars (Bouvier+, 2001)J/A+AS/109/29 : Very low mass stars in Praesepe (Hambly+, 1995)J/A+AS/129/9 : Delta Sct stars in Praesepe (Pena+ 1998)J/AJ/106/637 : ICCD speckle observations.
