  • Star Clusters/Associations. I. Associations

    The catalog contains data and bibliographical citations for all 70 associations of the second edition of the "Catalogue of Star Clusters and Associations (CSCA)" edited by Alter...
  • The Cluster System of the LMC

    A new catalogue of clusters in the Large Magellanic Cloud has been constructed from searches of the IIIa-J component of the ESO/SERC Southern Sky Atlas. The catalogue contains...
  • Proper Motions and UBV Photometry in h+{chi} Per

    Proper motions with an 80 year baseline have been determined relative to reference stars with B=13.9mag. determined for 3086 stars brighter than B=15.5mag. within an area of 50'...
  • Extended Hipparcos Compilation (XHIP)

    The Extended Hipparcos Compilation (XHIP) cross-references the New Hipparcos Reduction (HIP2, Cat. I/311) with relatable data from a broad survey of presently available sources....
  • Star clusters in IC 10

    Based on our observations with the 6-m BTA telescope at the Special Astrophysical Observatory, the Russian Academy of Sciences, and archival Hubble Space Telescope images, we...
  • Kinematics of Sco-Cen OB Association

    A fine structure related to the kinematic peculiarities of three components of the Scorpius-Centaurus association (LCC = Lower Centaurus-Crux, UCL = Upper Centaurus-Lupus, and...
  • Kinematics of Gould Belt Based on Open Clusters

    We have redetermined kinematic parameters of the Gould Belt using currently available data on the motion of nearby young (logt<7.91) open clusters, OB associations, and...
  • Close binary system EQ Ori

    The results of a UBVR photometry observations are presented for eclipsing variable EQ Ori. The binary was observed 1988 with the 1-m telescope at Maidanak Observatory (Uzbekistan).
  • KV Cyg, V435 Cyg, V699 Cyg UBVR photometry

    The results of a UBVR photometry observations are presented for eclipsing binaries KV Cyg, V435 Cyg and V699 Cyg. Each binary was observed 1989/91 with the 60 cm telescopes at...
  • New list of OB associations

    A new partition into associations of OB stars within 3kpc of the Sun is derived using Battinelli's modification of the cluster analysis method. We have found 58 associations, of...
  • BVR CCD photometry on NGC 1777

    We present photographic (B and V) and CCD (B, V, and R) photometry of stars in the remote LMC cluster NGC 1777, and integrated UBV photometry of the inner part of the cluster. A...
  • Newly identified star clusters in M 31

    Using the HST archives, we have searched portions of the southern half and northwest quarter of the Andromeda Galaxy (M 31, NGC 224) for previously unrecognized star clusters....
  • HII regions in OB associations

    Using the data from the NOAO Local Group Survey, we have measured the H{alpha} fluxes of 291 nebulae associated with 21 of the van den Bergh OB associations. We have combined...
  • C,T1 photometry of 6 LMC clusters

    As part of an ongoing project to investigate the cluster formation and chemical evolution history in the Large Magellanic Cloud (LMC), we have used the CTIO 0.9m telescope to...
  • HST WFPC2 star clusters in M31. III.

    This paper describes the results of a Hubble Space Telescope (HST) WFPC2 search for star clusters in active star-formation regions of M31. Nine of the clusters were previously...
  • JHK photometry in Cluster [BDS2003] 107

    We present new near-infrared classification spectra for nine candidate members of the galactic cluster [BDS2003] 107 (Cluster 107) observed with the IRTF SpeX instrument. We can...
  • HST WFPC2 star clusters in M31. II.

    This paper reports on a survey of star clusters in M31 based on archival images from the Hubble Space Telescope. Paper I reported results from images obtained with the Wide...
  • HST WFPC2 star clusters in M31

    As a followup to the automated cluster search carried out by Williams & Hodge (2001ApJ...548..190W), we have examined 39 Hubble Space Telescope Wide Field Planetary Camera 2...
  • Subaru NIR obs. of Pleiades stars in SEEDS survey

    We find a new substellar companion to the Pleiades member star, Pleiades HII 3441, using the Subaru telescope with adaptive optics. The discovery is made as part of the...
  • SiO and H2O masers in Stephenson 2 cluster

    We present the results of radio observations of red supergiants in a star cluster, Stephenson (1990AJ.....99.1867S)'s #2 (Cl Stephenson 2), and of candidates for red supergiants...
