A SPECTRUM OF THE VEILED T-TAURI STAR CY-TAU

We present a flux calibrated spectrum of the star listed as CY Tau in the ''General Catalogue of Variable Stars 4th ed.'' (Kopolov et al. 19 87) in the spectral range 3700 angstrom less-than-or-equal-to lambda l ess-than-or-equal-to 6400 angstrom with a resolution of almost-equal-t o 15 angstrom showing the Balmer-Series from H(beta) to H10 as well as the CaII H (in blend with H(epsilon)) and K lines in emission. Apart from the emission lines the spectrum is composed of a continuum equiva lent to that of an ordinary pre-main sequence star (i.e. a ''naked'' T Tau) of spectral type M2 V with emission lines plus a ''blue'' veilin g continuum that can be described as black body radiation of temperatu re T(BL) almost-equal-to 7000 K due to accretion onto a boundary layer at a rate of M(acc) greater-than-or-similar-to 2.8 10(-8) M . a-1.
