Hipparcos Intermediate Astrometric Data (IAD) have been used to derive astrometric orbital elements for spectroscopic binaries from the newly released Ninth Catalogue of...

This table contains space weather data based on 360 interplanetary shocks (forward and reverse) observed by ACE during the 80 month time period from January 1998 to August 2004....

In our paper we present VLT-observations in R, I and J of the candidate companion of PSR B1718-19, and also make use of HST observations in F702W, previously presented in Van...

Magnetized stars usually exhibit periodic variations of the effective (longitudinal) magnetic field B_e_ caused by their rotation. We present a catalog of magnetic rotational...

We present the catalogue of 112 massive isolated white dwarfs, both magnetic and nonmagnetic, with masses M>0.8M_{sun}_. Mass determinations and other parameters of white...

Spatially resolved CCD photometry of the Q2237+0305 gravitationally lensed quasar in V, R and I spectral bands from observations with the Maidanak 1.5-m telescope made in...

We present new optical and infrared observations of the counterpart to the Anomalous X-ray Pulsar (AXP) 4U 0142+61 taken with the Keck I telescope. The counterpart is found to...

Fitting parameters for the phase resolved spectra of the 2000 and 1998 observation are given. The model in use is the Negative Positive EXponential (NPEX) model (with Gamma_2_...

A long-term photometric monitoring of a selected sample of solar analogues has been carried out since early nineties as part of "The Sun in tim" project, which is aimed at a...

We present optical R-band light curves of the gravitationally lensed quasar SBS 1520+530 derived from data obtained at the Nordic Optical Telescope, from February 1999 to May...

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,...

We present 850{mu}m imaging polarimetry of the W51A massive star forming region performed with SCUBA on the James Clerk Maxwell Telescope (JCMT) situated close to the summit of...

Files table4.dat contain calculated Stokes IQUV local line profiles of Fe II 4923.9 shown in Fig. 4 of this paper. Profile sets are provided for 0.1, 5 and 20kG magnetic fields,...

Using speckle-interferometry we have carried out repeated measurements of relative positions for the components of 34 T Tauri binary systems. The projected separation of these...

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,...

We present a new survey of the radial oscillation modes of neutron stars. This study complements and corrects earlier studies of radial oscillations. We present an extensive...

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

We report on a pre-eclipse dip of the X-ray binary pulsar Her X-1 observed by the Rossi X-ray Timing Explorer (RXTE) in 1996 July. The energy spectra in the 3-18keV range can be...

The paper gives orbits and masses for some 200 nearby visual binaries, as derived from combining ground-based and Hipparcos data. Table 6 gives identifications and notes, and...

We present a set of evolutionary tracks for white dwarfs with helium cores in the mass range from 0.179 to 0.414M_{sun}. The tracks are based on a 1M{sun}_ model sequence...
