6 Dec 1996 | | Subject: | astro-ph | | Affiliation: | Brera Observatory, Milano, Italy), C. Akan (Ege University, Turkey), M. Bossi (Brera Observatory, Milano, Italy), C. Koen (SAAO, South Africa), K.Krisciunas (JAC, Hawaii, USA), E. Rodriguez (IAA, Granada, Spain | | Abstract: | A multisite campaign involving five observatories allowed us to solve the light curve of the Gamma 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 Gamma Dor stars, it seems that g--mode pulsators can be found near the cold border of the instability strip. | | Source: | arXiv, astro-ph/9612063 | | Services: | Forum | Review | PDF | Favorites | |
