We present a list of 130 Galactic Open Clusters, found in the All-Sky Compiled Catalogue of 2.5 Million Stars (ASCC-2.5). For these clusters we determined a homogeneous set of...

We subjected 106 new high-resolution spectra of the double-lined spectroscopic close binary epsilon Lupi, obtained in a time-span of 17 days from two different observatories, to...

We present the minor-axis kinematics of ionized gas and stars for a sample of 5 spiral galaxies, which are characterized by either a zero or a shallow gas velocity gradient...

We present the results of spectroscopic follow-up observations for a sample of 71 red objects with high proper motions in the range 0.08-1.14 arcsec/yr as detected using APM and...

Continuum emission at 450 and 850{mu}m from warm dust has been mapped in the fields of 71 methanol masers. Within these fields lie 30 centimetre-wave radio continuum sources and...

Here are the 69 radial-velocity measurements of GJ 777A (HD 190360) used for deriving the orbital solution of this star. These velocities were obtained using the ELODIE echelle...

Here we list our 254 ELODIE + 5 CORALIE measurements obtained for the 6 stars with planetary companions presented in the paper. ELODIE is a high-resolution (42000) fiber-fed...

Dust- and gas mass loss rates and distances are determined for a sample of about 330 infra-red carbon stars that probe a distance up to about 5.5kpc. The dependence of the dust-...

The radial-velocity observations were made during the years 1989-1997 with the photoelectric scanner CORAVEL (Mayor, 1985IAUCo..88...35M) on the Danish 1.54-m telescope at ESO,...

An analysis of 1236 new electronic spectra of the eclipsing binary EN Lac from four observatories and of 994 radial velocities (RV hereafter) from photographic spectra,...

Hipparcos trigonometric parallaxes fix distances to individual stars in the Hyades cluster with an accuracy of about 6 percent. We use the Hipparcos and Tycho-2 proper motions,...

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...

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 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...
