- Description:
- The list contains a total of 131 binaries (115 systems) belonging to the halo or high-velocity disk. Of these, 122 correspond to wide binaries, that is, binaries with expected major semiaxes larger than 25 AU. The catalogue was constructed by identifying common proper-motion companions to the high-velocity and metal-poor stars studied by Schuster and collaborators (SN: Schuster and Nissen 1988A&AS...73..225S, SPC: Schuster, Parrao and Contreras, 1993, Cat. <J/A+AS/97/951>). Based on Stromgren photometry, Schuster et al. obtained distances, metallicities and ages for their stars. For each star of the SN and SPC catalogues a machine search for common proper-motion companions was made among the NLTT (Cat. <I/98>) stars within 12 minutes of arc. This initial list was checked to avoid errors due to misidentifications, duplicate entries, etc., and was supplemented with some companions listed in the LDS (Luyten, 1987, Cat. <I/130>) and not present in the NLTT (mostly from the southern hemisphere), as well as with additional common-proper- motion companions found in the CCDM (Dommanget and Nys, 1994, Cat. <I/211>). Additional close companions found in the CCDM were retained only if an orbit was given, or if their separations were of less than 1". Wider companions were usually eliminated, unless convincing evidence of their sharing the proper motion of the primary was found. Distances to the primaries were updated using the Hipparcos (Cat. <I/239>) catalogue. The data in the list are as follows (for details see the main paper): The first column contains the Hipparcos number, when available. Column 2 contains other identifications of the star. In the third column its multiplicity is indicated. Column 4 contains the adopted distance to the star. Columns 5 and 6 contain the absolute visual magnitudes of the primary and secondary, respectively. The angular separation between the components is given in Column 7, and the expected value of the major semiaxes in Column 8. Columns 9 and 10 contain the metallicity of the primary and its age, as determined by Schuster and collaborators. The individual ages listed were kindly provided by W. J. Schuster. The peculiar velocity of the binary is given in Column 11. Columns 12 to 15 contain the main galactic orbital parameters; we list the apocentric distance, Rmax, as well as the maximum distance away from the galactic plane reached by the star |zmax|, and the three-dimensional eccentricity e of its galactic orbit. The last column contains various notes.

- Description:
- This is the second edition of the Catalogue of the Components of Double and Multiple stars (CCDM). The first one, of which a detailed description has been given in Communication de l'Observatoire Royal de Belgique, Serie A, 115, 1994, may be found at the CDS under reference <I/211>. The complete description of this second edition is published (in French and English) in "Observations et Travaux", a review edited by the Societe Astronomique de France. A detailed historical sketch of the creation and development of the catalogue -- which served as double star data base for the preparation of the HIpparcos Input Catalogue <I/196> -- has been published in issue 25, pp.29-31 (1999) of this same review. There are no fundamental differences between the two editions: format, presentation and construction are similar. The main difference lies in the important increase of the considered systems of which number expands from 34.031 to 49.325. Few additions exist in the description of the contents of the various columns, and some new codes had to be used for references to astronomical positions, especially related to the introduction of new Hipparcos systems or components to known systems (see the "refpos.dat" file). Concerning the names of the systems in columns 16 to 22, one has also to mention some additions to those given in the INDEX-WDS (C.E.Worley, 1984). They are: AOT = Oss. di Torino ACG = Astr.Cat.Greenw. BAC = P.Bacchus BEW = U.Bastian et al. CRI = F.Crifo DUF = M.Duflot DYL = J. Doyle HDS = Hipparcos JRN = A. Jorissen JKS = M.P.Jenniskens KZA = S.M.Kazeza LMP = P.Lampens LYS = L. Louys MCO = McCormick NYS = O.Nys ONL = Occult. News Letters PWS = Th.Pauwels RSU = M.Rousseau SLE = G.Soulie VHS = P.Verhas Note that: MAL = McAlister in WDS 1984 MCA = McAlister in WDS 1994 Some changes have finally been brought to the names of particular STT and STF systems (App) as shown here, to avoid some confusion that exists with the non (App) systems: --> For STF (App)I, addition of 4000, i.e. STF 4001 instead of STF 1(App)I STF 4002 instead of STF 2(App)I ............... STF 4060 instead of STF 60(App)I --> For STF (App)II, addition of 5000, i.e. STF 5003 instead of STF 3(App)II ............... STF 5012 instead of STF 12(App)II --> For STT (App)I, addition of 4000, i.e. STT 4001 instead of STT 1(App) STT 4005 instead of STT 5(App) ............... STT 4256 instead of STT 256(App)

- Description:
- The introduction to this catalogue has been the subject of a publication in the "Communications de l'Observatoire Royal de Belgique" (Serie A, number 115). Detailed are: its origins, its aims, its realization, the search of identifiers, the compilation of astrometric data and the related problems as well as the fundamental ties between the CCDM and the HIPPARCOS INPUT CATALOGUE (HIC). It also contains a complete bibliography of the referred papers. The contents of the general catalogue (63,463 systems) is also described as well as the conditions of its availability to the astronomical community and the projects underway for the next edition. For all these items, the user is invited to refer to this publication because hereafter only the format and the contents of the catalogue follow. To identify the systems and their components, we adopted the clever numbering process of the authors of the INDEX consisting in combining the right ascension and declination, respectively limited to 0.1 minute of time and to 1 minute of arc. In order to distinguish the CCDM numbers from the INDEX numbers - in addition to their different equinox: 2000 for the CCDM and 1900 for the INDEX - we adopted the signs + and - instead of the letters N and S for separating the coordinates. Consequently, in the INDEX and in the CCDM, one entry is devoted to a same system but the contrary to the INDEX, where a sub-entry is assigned to each group of two components, whatever the multiplicity of the system may be, the CCDM allows one sub-entry and thus one record per component. The present edition contains only the 34,031 systems (table below, part I) for which an accurate position has been found for at least one component. The catalogue extends thus much over the sample of the somewhat 14,000 systems finally retained for the HIPPARCOS INPUT CATALOGUE and assembled in its Annex 1.

- Description:
- The results of classical CCD observations for 371 double or multiple stars (450 pairs) obtained at both, Serbian Astronomical Station on the mountain of Vidojevica (ASV) and Bulgarian National Astronomical Observatory at Rozhen (NAOR) are presented. At ASV the observations were performed with the 0.6 m telescope in the first half of 2016 during 11 nights, and with the newly mounted 1.4 m telescope in the second half of 2016 during 16 nights. At NAOR, the observations were performed with the 2 m telescope during four nights. In this paper, we present 477 measurements (position angle and angular separation) for these 450 pairs. Among them there are 41 pairs with published orbital or linear elements and residuals are given for them. Some pairs have measurements for several epochs. Our observed pairs have angular separations in the interval from 1.60" to 190.30", with a mean angular separation of 14.87" and a median value of 4.34". Two new pairs and linear elements for four pairs which are calculated for the first time are also presented.

- Description:
- Using the 2m telescope of the Bulgarian National Astronomical Observatory at Rozhen, observations of 222 double or multiple stars were carried out during three nights in 2011. This is the sixth series of measurements of CCD frames of double and multiple stars obtained at Rozhen. Also in 2011, using the 0.6m telescope of the Serbian Astronomical Station on the mountain of Vidojevica, observations of 208 double or multiple stars were carried out during six nights. This is the first series of measurements of CCD frames of double and multiple stars obtained at this station. In this paper, we present the results for the position angle and angular separation for 337 pairs and residuals for 72 pairs with published orbital elements or linear solutions. These observations have angular separations in the range from 1.37'' to 172.81'', with a median angular separation of 7.66''. We also present the recalculated linear solutions for four pairs and one linear solution that has been calculated for the first time.

- Description:
- We present 18365 astrometric observations of 290 visual binaries obtained with the 26-inch refractor of Pulkovo Observatory during 2014-2019. The separation between components is from 1.3" to 37" with a median value of 4.8". For a single observation, the mean separation error is 0.013", and the mean position angle error is 0.44{deg}/rho, where rho is an angular distance in arcseconds. We compare the observations of sample stars with the data from the Gaia DR2 catalog and the results of the ground-based observations performed with other telescopes.
