Spectroscopy of HD 4004. Correlated profile variations?

We present results of detailed analysis of spectral variability observed in the optical spectrum (lambda lambda 4350-5700 Angstrom) of HD 4004 (WR 1). Basing on data obtained during spectroscopic monitoring of this object in three nights in September 1994, and six nights in November 1995 we show tha t the variations observed in He II lines lambda 4542, 4686, 4860 and 5411 a re very similar and well correlated. We also show that the amount of variab ility in these lines is identical. We provide evidence, however, that the v ariations as observed in those He II show also noticeable differences. The projected velocities of perturbations exposed on He II emission line profil es do not scale with line width (FWHM). This means that the factor responsi ble for the observed profile variations is not coupled with the wind and it s velocity law. Based on our results we argue for two-component (fast-slow) wind model of HD 4004.
