Wolf-Rayet and O-star runaways kinematics
Reliable systemic radial velocities are almost impossible to secure for Wolf-Rayet stars, difficult for O stars. Therefore, to study the motions - both systematic in the Galaxy... -
Hyades membership
We use absolute trigonometric parallaxes from the Hipparcos Catalogue (Cat. ) to determine individual distances to members of the Hyades cluster, from which the 3-dimensional... -
Radial velocities of Cartwheel Galaxy
We report on high spectral and spatial resolution kinematic observations of H{alpha} emission from the Cartwheel system obtained with a scanning Fabry-Perot interferometer.... -
Spectroscopic data of 4 Herculis
A collection of spectroscopic data of 4 Her at our disposal (RV and spectrophotometric measurements) consist of spectra obtained at the Ondrejov and Haute Provence... -
Centaurus cluster velocities
Based on the photometric survey of the inner region of the Centaurus cluster (Jerjen & Dressler, 1997, Cat. ) we measured redshifts for a deep, surface brightness limited... -
High-resolution spectra south of Taurus
Listed are results from our high-resolution data for all stars in our study area which were listed by either Magazzu et al. (1997A&AS..124..449M) or Alcala et al.... -
Melotte 71 red giants radial velocities
New CORAVEL radial-velocity observations and UBV photometry of 24 red giants in the field of the intermediate-age open cluster Mel 71 are analysed for membership and duplicity.... -
Radial velocities of Pleiades members
The analysis of CORAVEL radial velocities of 93 stars selected on the basis of their proper motion and Geneva CCD photometric observations for 57 stars have permitted to... -
Radial velocities of 10 spectroscopic binaries
We present new orbits for ten (single-lined) spectroscopic binaries in seven open clusters: NGC 2489, 2567, 3033, 5822, 6134, 6664 and IC 2488 based on 243 individual radial... -
HI survey of polar ring galaxies. II.
We present the results of a neutral hydrogen survey conducted with the 100-m radiotelescope at Effelsberg of 44 northern objects in the polar-ring galaxy atlas of Whitmore et... -
Radial velocities & photometry of classical Cepheids
Radial velocities and distances have been measured for a sample of 48 remote classical Cepheids located in the outer disc of the Galaxy (118deg -
Binarity among B-stars in NGC 6231
We have measured radial velocities for 53 B-type stars, between B1 and B9, in the young open cluster NGC 6231 through a cross-correlation technique with synthetic spectra. Two... -
Cataclysmic variables systemic-velocity
We have collected {gamma} velocities of cataclysmic variables from a survey of published orbital radial-velocity studies. We argue that for the non-magnetic cataclysmic... -
Beta Lyr radial velocities and UBV data
A preliminary analysis of an extensive collection of interferometric, spectroscopic and photometric observations of the bright Be star {beta} Lyr lead to the following main... -
Line profile variations in eta Ori
Eta Orionis (HD35411) is a multiple system which consists of at least four early B-type stars. In the present paper we focus on the double-lined spectroscopic eclipsing pair... -
55 UMa spectroscopic orbit
The first investigation of the known triple system 55 UMa (2.55d binary in a ~1870-d orbit with the third star) based on electronic spectra led to several new findings about the... -
Velocities of red giants in NGC 2099
474 radial-velocity observations and new UBV photoelectric data for 55 and 20 red giants respectively, in the field of the intermediate-age open cluster NGC 2099 are presented... -
Photometry and radial velocities of 16 Lac
Photometric and spectroscopic observations of the {beta} Cephei star 16 Lacertae obtained in 1983 and 1984 are presented and analysed. Using all the published maxima we have... -
