Abstract: We present the results of our study of the poorly known B[e] star AS 160 = IRAS 07370– 2438. The high-resolution spectrum obtained with the 6-m BTA telescope exhibits strong emission in the Ha line with a two-component profile, indicating that the gaseous envelope of the star is non-spherical. Previously nonanalyzed photometric data suggest the presence of a compact dust envelope. The fundamental parameters of the star (log L/L = 4.4 ± 0.2, v sin i = 200 km s-1) and its distance (3.5 ± 0.5 kpc) have been determined for the first time and are in agreement with published estimates of the MK spectral type of the object (B1.5 V:). Analysis of the object’s properties leads us to suggest that this is a binary system that belongs to our recently identified type of Be stars with warm dust.
