J/A+A/378/113       Ap stars periodicity                     (Catalano+, 2001)

Fifth supplement to the catalogue of observed periods of Ap stars. Renson P., Catalano F.A. <Astron. Astrophys. 378, 113 (2001)> =2001A&A...378..113R
ADC_Keywords: Stars, Ap Keywords: catalogs - stars: chemically peculiar - stars: early-type - stars: variables: general Abstract: New data on the periods of Ap stars with references are presented. 161 further stars are introduced for which a periodic variability has recently been discovered or 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. File Summary:
