More on the pulsation period of the cool component in the symbiotic binary AG Dra.
FRIEDJUNG M., GALIS R., HRIC L. and PETRIK K.
Abstract (from CDS):
We have combined recent radial velocity measurements of Fekel et al. (2000AJ....120.3255F) with previously studied older ones, to test for the continued presence of the second period, found by Galis et al. (1999A&A...348..533G), which could be due to pulsations of the cool component of the AG Dra binary system. Fekel's data, even taken by themselves, also marginally suggest the presence of variations near the previously found second period. The period is in any case clearly seen, when all radial velocity measurements are combined.
