Scientific paper

The short and long wave spectrum (1150-3000 Å) of the central supermassive object in the 30 Doradus Nebula, R 136a, is analyzed. The equivalent widths of the lines attributed to R 136a are tabulated. The P Cyg lines of C IV, N IV, N V , He II and Si II of the stellar wind of R 136a are presented. The mass loss rate M= 3×10-4M_sun;/yr is derived from the line profiles of C IV and N IV by line fitting assuming ionization equilibrium.
