Spectral Classification of Stars in A Supplement to the Bright Star Catalogue
MK spectral types are given for about 584 stars in A Supplement to theBright Star Catalogue. These are compared with Hipparcos parallaxes tocheck the reliability of those classifications. The estimated errors are+/-1.2 subtypes, and 10% of the luminosity classes may be wrong.

A revised catalogue of delta Sct stars
An extensive and up-dated list of delta Sct stars is presented here.More than 500 papers, published during the last few years, have beenrevised and 341 new variables have been added to our last list, sixyears ago. This catalogue is intended to be a comprehensive review onthe observational characteristics of all the delta Sct stars known untilnow, including stars contained in earlier catalogues together with othernew discovered variables, covering information published until January2000. In summary, 636 variables, 1149 references and 182 individualnotes are presented in this new list. Tables 1 and 2 will be accessibleonly in electronic form at the CDS via anonymous ftp tocdsarc.u-strasbg.fr (130.79.128.5) or viahttp://cdsweb.u-strasbg.fr/Abstract.html

A catalogue of variable stars in the lower instability strip.
Identifications, positions, photometry, spectra, some pulsationalfeatures, other astrophysical parameters and literature for 302pulsating variable stars in the lower instability strip, near the ZAMS,are given. About 185 stars have near homogeneous photometric informationin the Stroemgren's uvby-β photometric system. Thiscatalogue/database covers information published until November 1993.

Study of Delta Scuti stars in the Geneva photometric system. I - New photometric data and period analysis for nine stars
Results are presented of the period analyses for nine Delta Scuti stars,of which six are new short-period variable stars. For some of thesestars, extensive data sets covering time bases of the order of two yearsor more were obtained. The results from year to year are consistent withthe multiperiodic solution derived from the combined data for thosestars with the largest data sets. In some cases of less frequentlyobserved stars, the results are not always compatible with one another.It is suggested that, generally, this is due to insufficient datasampling or too narrow time bases. The fact that many unevolved orslightly evolved Delta Scuti stars are multiperiodic with very smallamplitudes of a couple of hundredths of a magnitude is confirmed.
