The frequency analysis of some selected beta cephei stars

In this study, the frequency analysis of the variable stars classified as candidate Beta Cephei stars in INTEGRAL satellite and ASAS (All Sky Automed Survey) database was performed. According to the results obtained from the frequency analysis, these stars in the ASAS database were listed as definite and suspicious Beta Cepheids. The photometric observation of ASAS 162643+2329,7 and ASAS 011024+2719,3 in the list of suspicious Beta Cepheids, were made. The nature and parameters of pulsation for these targets were determined from their frequencies analysis. ASAS 162643+2329,7 and ASAS 011024+2719,3 have shown pulsation with two and three frequencies, respectively. And also, the photometric observation of NSV 13054 star selected from Beta Cephei catalogues prepared by Handler and Stankov (2005) was made. According to its frequency analysis, NSV 13054 star has shown pulsation with one frequency.In the final stage of the study, the catalogue of Beta Cephei variables prepared by Handler and Stankov (2005) was updated. 134 new discovered Beta Cephei stars and updated parameters of all variables added to the catalogue. The distributions of spectral type, luminosity class, pulsation period and amplitude were plotted using the catalogue parameters. A meaningful change was determined between the pulsation amplitude and rotation velocity of the target stars.
