Effective collision strengths for transitions between 52 fine structure states calculated in a Breit-Pauli approximation are provided in ups.dat. Results are provided for logT...

Astrometric photographic positions of the Saturnian satellite Helene obtained from 22 plates taken in 6 nights are presented. The observations are distributed between 5 missions...

In January 1997, at the Observatsrio Nacional (ON), Rio de Janeiro, Brazil, digital CCD observations of the solar diameter began with a Danjon astrolabe adapted for solar...

File table1 is a list of theoretical data for the broadening of metallic lines by collisions with neutral hydrogen atoms. The list contains data for 4891 spectral lines between...

This table presents relative proper motions and positions for 166 Luyten Catalogue stars re-discovered as a result of search for high proper motion stars in the southern...

Collisional rate coefficients for rotational transitions in C3H2 and SiC2 due to collisions with H2 molecules are calculated. The C3H2 has two distinct species, ortho and para,...

The tables display the total emission probabilities, the total dissociation probabilities and the mean kinetic energies released in the dissociation for the rovibronic levels of...

The absolute K magnitudes and kinematic parameters of about 350 oxygen-rich Long-Period Variable stars are calibrated, by means of an up-to-date maximum-likelihood method, using...

Using the semiclassical perturbation approach, we have calculated electron-, proton- and He II-impact line widths and shifts for 32 Zn I multiplets as a function of temperature...

Using the semiclassical perturbation approach, we have calculated electron-, proton-, He II-, Mg II-, Si II- and Fe II-impact line widths and shifts for 189 Ca I multiplets as a...

The Appendix contains 318 galaxies, 15 of them with Vo>500km/s but D<10Mpc, and 28 dwarf spheroidals without Vo but highly probable members of nearby groups. Cone search...

Astrometric positions of the first eight Saturnian satellites obtained from 138 photographic plates taken in 30 nights in the years 1982 to 1988 are presented. All positions are...

This table presents relative proper motions and positions for 293 stars with proper motions larger than 0.15 arcsec/year, discovered as a result of a program to identify fast...

We present an Echelle+CCD high resolution spectroscopic atlas mapping the MKK classification system over the wavelength interval lambda 8500-8750 A, centered on the near-IR...

As part of a systematic study of the collisional properties of Fe ions carried out by the IRON Project, electron excitation rates (effective collision strengths) are computed...

We present angular separations, position angles and {Delta}V instrumental magnitude differences of 83 visual double stars with angular separations around two arcseconds. Our...

229 CCD positions of Nereid taken between 1993 and 1998 are presented. Many of the observations were taken near the periapsis. Considering also the other published positions we...

We have observed 42 Herbig Ae/Be stars candidates in both hemispheres using the high resolution spectrographs AURELIE and ELODIE at OHP, and CES at ESO. Table 1 present the...

Collision strengths and Maxwellian-averaged rate coefficients have been calculated for 3,160 non-vanishing transitions among 80 fine structure levels, dominated by...

We present the measurements of 49 visual double stars made in 1997 with the 50 cm refractor of the Nice Observatory (Table 1). A CCD camera was attached to this refractor. Some...
