Periodicity of the spectrum variable omega Oph.
Abstract
Periodicity of the Spectrum Variable w Oph Summary. UBV photometric measures of Oph show that the luminosity varies periodically. The period is probably a little less than 06.75 or 36.0. Other observations are necessary to remove the ambiguity between these associated periods. Key words: Ap star periodicity photometric variations
