Scientific paper

The CFHT Fourier transform spectrometer was used to search for the presumed cool luminous giant companions of two well-known Be shell stars Zeta Tau and KX And during August 27-30, 1985 in the K-band. These stars are possibly prototypes of interacting Be stars with a cool companion. In the case of Zeta Tau, the observed IR flux is insufficient to indicate the presence of a cool luminous star which overflows its Roche lobe. However, in the case of KX And, the observed IR energy distribution is compatible with such a companion.
