VLBA ASTROMETRY OF THE AeBe STAR EC 95 IN SERPENS
We present an analysis of eleven VLBA observation of the binary system EC 95 covering a total observing time span of 2.5 years. Both sources in the system were detected a sufficient number of times to allow for high quality independent astrometric fits. The trigonometric parallax obtained from these...

| Resumo: | We present an analysis of eleven VLBA observation of the binary system EC 95 covering a total observing time span of 2.5 years. Both sources in the system were detected a sufficient number of times to allow for high quality independent astrometric fits. The trigonometric parallax obtained from these fits corresponds to a distance d = 429 ± 2 pc. Our observations further suggest that both components in EC 95 could be young stellar objects of intermediate mass. |
