File table2.dat contains the 74 new measured radial velocities of the primary component of the SB2 HD 81009.

We report the case of the early-type disk galaxy NGC 4672 as a new example of a galaxy characterized by the orthogonal geometrical decoupling between bulge and disk. The...

Here we list the CORALIE radial-velocity measurements for HD 75289 and HD 130322. CORALIE is a fiber-fed echelle spectrograph designed for high-precision radial-velocity...

CORAVEL radial-velocity observations of Am stars in the Hyades and Praesepe have allowed the determination of orbital elements for 10 spectroscopic binaries, among which 3 are...

New memberships, mean parallaxes and proper motions of all 9 open clusters closer than 300pc (except the Hyades) and 9 rich clusters between 300 and 500pc have been computed...

Internal kinematics, spectroscopic binaries and galactic motion are investigated for the trapezium system BD+00 1617 (which lies at the heart of the young open cluster Bochum 2)...

We present the stellar and ionized-gas velocity curves and velocity-dispersion profiles along the major axis for six early-type spiral galaxies. Two of these galaxies, namely...

In Table 1 we present our group catalog. For each group we list the ID number (column 1), the number of members (column 2), the coordinates {alpha}(1950) and {delta}(1950)...

The light curves of the first overtone Pop. I Cepheids (s-Cepheids) show a discontinuity in their {phi}21 vs. P diagram, near P=3.2day. This feature, commonly attributed to the...

The results of an 18-year radial-velocity survey of 30 red giants in the field of the open cluster NGC 752 are presented. The membership of 15 stars is confirmed. Four...

We report on a detailed spectroscopic and photometric study of V1046 Orionis undertaken to resolve uncertainties about the period(s) and causes of the spectroscopic and...

The C I, Na I D, and H{alpha} lines of the post-AGB binary HR 4049 have been studied. Na I D variability results from a photospheric absorption component ([Na/H]=-1.6+/-0.2)...

We present new vsini measurements for 235 low-mass stars in the Pleiades. The differential rotational broadening has been resolved for all the stars in our sample. These...

A detailed model atmosphere analysis of high-resolution and high S/N CCD spectra of IIPeg has yielded for the first time a self-consistent set of fundamental parameters of the...

The radial velocity and light curves of 24 Cepheids in the Magellanic Clouds, with period in the range 30-134d, were Fourier decomposed with the aim of detecting resonance...

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...

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...

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....

We have used HIPPARCOS proper motions and the method of Statistical Parallax to estimate the absolute magnitude of RR Lyrae stars. In addition we used the HIPPARCOS parallax of...

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...
