Abstract
Theoretical spectral energy distributions are computed for a grid of hydrog en-deficient and carbon-rich model atmospheres with a range in T-eff of 400 0-5500 K and log g of 1.0-0.0, using the technique of opacity sampling, and taking into account continuous, atomic line and molecular band absorption. The energy distributions are compared with the spectrum of V4334 Sgr (Saku rai's object) of August 12, 1998 in the wavelength interval 300-1000 nm. Th is comparison yields an effective temperature of V4334 Sgr of T-eff = 5250 +/- 200 K, and a value for the interstellar plus circumstellar reddening of EB-V = 1.3 +/- 0.1.
