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
