Abstract:
We have calculated relative element abundances for a sample of 43
symbiotic stars. Helium abundances and the relative elemental
abundances N/O, Ne/O, Ar/O were derived from new spectra collected in
the optical range through low dispersion spectroscopy. The He ionic
abundances were derived taking into account self-absorption effects in
Balmer lines. We found that the symbiotic stars in the galactic bulge
have heavy element abundances showing the same wide distribution as
other bulge objects. In the galactic disk, the symbiotic stars follow
the abundance gradient as derived from different kinds of objects.
Description:
Spectroscopic observations were performed in two runs at the National
Laboratory for Astrophysics (Brasopolis, MG, Brazil) from 7-16 Jun.,
2002, and from 23-26 Jun., 2003, using a Boller & Chivens Cassegrain
spectrograph attached to the 1.60m telescope with a dispersion of
4.4Å/pixel. Some observations were made at ESO using the 1.52 m
telescope in La Silla, Chile (from 8-13 Oct., 2002) with a Boller &
Chivens Cassegrain spectrograph with a dispersion of 2.2Å/pixel.
Spectra cover the range 3800-7400Å.
