Doradus variables , a new class of pulsating stars . The case of HD 224945

A multisite campaign involving five observatories allowed us to solve the light curve of the γ Doradus star HD 224945. The multiperiodic content, the high frequency term at 3.00 c/d and the frequency spacing between the observed terms strongly support its pulsational nature. Considering the low frequency terms observed in γ Dor stars, it seems that g–mode… CONTINUE READING
