Scientific paper

High precision visibility curves for the T Tau system have been obtained in the K-band by speckle interferometric observations using a 32-element linear array detector. It is confirmed that the T Tau system consists of three infrared sources, which are a central optical/infrared star: T Tau (O), an infrared object: T Tau (S) at 0.6 arcsec south, and a faint stellar object: Tau (O-prime) at 0.4 arcsec north. Based on the present observations, as well as on published photometric data, decomposed spectral energy distributions of the individual sources are proposed. A predominant role for accretion disk luminosities is suggested.
