HST/STIS spectrum of AM CVn (black), disk spectrum (blue), and wind spectrum (red, T_wind = 35 000 K, Ṁ_wind = 5 × 10^-10 M_⊙ yr^-1, SV model). Note the prominent P Cygni profile of the N v 1240 Å line is not similar to that of the disk, but to that of the wind model. All models are reddened by E(B − V) = 0.12, and folded with a 1.2 Å Gaussian.
