Fourth supplement to the catalogue of observed periods of Ap stars
      Catalano F.A., Renson P.
     <Astron. Astrophys. Suppl. Ser. 121, 57 (1997)>
     =1997A&AS..121...57C      (SIMBAD/NED BibCode)
ADC_Keywords: Stars, Ap

Keywords: catalogs - stars: chemically peculiar - stars: variables: other


Description:
    New data on the periods of Ap stars with references are presented
    (Table 1). 21 further stars are introduced for which a periodic
    variability has recently been discovered or for which it was known
    before but it was not reported in previous issues of this catalogue.
    For many stars also present in previous issues of the catalogue new
    determinations of the periods are given. Recently attributed variable
    star names are also quoted.
    Note: this catalog is included in III/199
