Pulkovo compilation of radial velocities for 35495 stars in a common system. Not Available
| Absolute proper motions of open clusters. I. Observational data Mean proper motions and parallaxes of 205 open clusters were determinedfrom their member stars found in the Hipparcos Catalogue. 360 clusterswere searched for possible members, excluding nearby clusters withdistances D < 200 pc. Members were selected using ground basedinformation (photometry, radial velocity, proper motion, distance fromthe cluster centre) and information provided by Hipparcos (propermotion, parallax). Altogether 630 certain and 100 possible members werefound. A comparison of the Hipparcos parallaxes with photometricdistances of open clusters shows good agreement. The Hipparcos dataconfirm or reject the membership of several Cepheids in the studiedclusters. Tables 1 and 2 are only available in electronic form at theCDS via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or viahttp://cdsweb.u-strasbg.fr/Abstract.html
| Radial velocities. Measurements of 2800 B2-F5 stars for HIPPARCOS Radial velocities have been determined for a sample of 2930 B2-F5 stars,95% observed by the Hipparcos satellite in the north hemisphere and 80%without reliable radial velocity up to now. Observations were obtainedat the Observatoire de Haute Provence with a dispersion of 80Ä,mm(-1) with the aim of studying stellar and galactic dynamics.Radial velocities have been measured by correlation with templates ofthe same spectral class. The mean obtained precision is 3.0 km s(-1)with three observations. A new MK spectral classification is estimatedfor all stars. Based on observations made at the Haute ProvenceObservatory, France and on data from The Hipparcos Catalogue, ESA.Tables 4, 5 and 6 are only available in electronic form at the CDS viaanonymous ftp to cdsarc.u-strasbg.fr or viahttp://cdsweb.u-strasbg.fr/Abstract.htm

| Are luminous asymptotic giant branch stars all of spectral type MS? - Evidence from spectroscopic and photometric observations of LMC stars A sample of stars that included luminous supergiants and AGB stars wasexamined for spectral differences between these two star types; thespectra include those of 49 LMC stars previously classified as M stars,eight red stars in NGC 2100, and one known LMC S star. A closeexamination of image-dissector-scanner spectra revealed a great numberof stars with enhanced ZrO bands, which were classified as MS. A totalof nine AGB stars more luminous than M(bol) = -6 were found, the mostluminous at M(bol) = -6.6. In the region of M(bol) between -5 and -6.6,no star was found showing a normal M-type spectrum; this region isoccupied by MS, S, and C stars. The luminous stars of the M(bol) lessthan -5.5, are from their brightness and pure M-type spectra massivesupergiants; all NGC 2100 stars belong to this group.
