Abstract:
We present here the preliminary results of the long term monitoring of the optical spectrum of symbiotic stars from the Vainu Bappu Observatory. Spectra of EG and, AX Per, BX Mon, RX Pup, Rw Pup, RW Hya, AS 210, and StHα 149, were obtained during 1999-2002. The spectral type of the secondary is estimated on the basis of the observed absorption indices.
