Abstract:
A comparison of synthetic spectra for cool giants with the observed
broad-band optical/IR photometry is suggested to estimate the effective
temperature, T_eff, of cool components in symbiotic binaries. The uncertainties
of such estimates are within a range of 100-300 K. Here we demonstrated this
approach on EG And and AX Per, and found T_eff (EG And) = 3 500 +200/-100 K and
T_eff (AX Per) = 3 400 +/- 150 K. These results agree well with those obtained
from empirically determined dependencies of effective temperature upon spectral
type.
