Chemical abundances of southern symbiotic stars.

PEREIRA C.B.

Abstract (from CDS):

Allen's (1984) optical spectra of symbiotic stars were used in order to derive some elemental ratios and He abundances. The studied systems were those for which spectrophotometry was available in his catalogue, i.e. LMC S63, Y Cra, SS 29, He2-104, SS 38, He2-106, V455 Sco, He2-127, He2-171, AE Ara, SS 122 and Hen 1242 (=KX TrA). Estimates for the temperature and luminosity of the hot components are given. UV spectra taken with the IUE satellite were also used for the propose of abundance and temperature determination. The study shows that the analyzed systems have abundance ratios given by He/H, Ar/O, Ne/O, N/O and Fe/Ne and temperature and luminosities typical for other symbiotic systems. For one symbiotic system, SS 29, oxygen is underabundant. The symbiotic stars H1-36, Allen (1983) and CL Sco Blair et al. (1983) were also included in this work.
