Özet

We present the first comprehensive catalog of the ? Doradus type pulsating stars. This catalog covers observational properties of all ? Dor variables obtained until January 2017. The photometric and physical properties of 109 well-known ? Dor pulsators, 18 hybrid stars, 13 anomalous ? Dor stars, and 22 ? Dor stars in eclipsing plus 1 non–eclipsing SB2 binary systems are presented as separate tables. In addition, 291 candidate ? Dor variables discovered by CoRot, 307 candidate ? Dor, 205 hybrid and 11 candidate ? Dor in binaries discovered by Kepler were also presented. Distribution of the genuine single ? Dor pulsators in the Ppuls-Teff, Amplitude-Teff, Amplitude-Ppuls and L-Teff diagrams are presented and discussed. We find following correlations for the ? Dor pulsators in the eclipsing binaries: Ppuls ? Porb0.27, Ppuls ? Q0.45, and Ppuls ? r-0.44, where (Q) is the pulsation constant and r is the fractional radius of the pulsating component in the binary system. The correlation coefficients are not high enough due to limited sample and scattering in the data. © 2018 Elsevier B.V.
