Özet

We present the first comprehensive catalog of the gamma Doradus type pulsating stars. This catalog covers observational properties of all gamma Dor variables obtained until January 2017. The photometric and physical properties of 109 well - known gamma Dor pulsators, 18 hybrid stars, 13 anomalous gamma Dor stars, and 22 gamma Dor stars in eclipsing plus 1 non-eclipsing SB2 binary systems are presented as separate tables. In addition, 291 candidate gamma Dor variables discovered by CoRot, 307 candidate gamma Dor, 205 hybrid and 11 candidate gamma Dor in binaries discovered by Kepler were also presented. Distribution of the genuine single gamma Dor pulsators in the P-puls-T-eff, Amplitude-T-eff, Amplitude-P-puls, and L-T-eff diagrams are presented and discussed. We find following correlations for the gamma Dor pulsators in the eclipsing binaries: P-puls proportional to P-orb(0.27), P-puls proportional to Q(0.45), and P-puls proportional to 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.
