Abstract. We present synthetic UV/optical NLTE spectra for the accretion disc in the ultra-compact LMXB 4U 1626-67. By assuming a radial alpha-disc structure, we perform full non-LTE radiative transfer calculations to compute the detailed vertical structure of the disc. Comparing our results with HST spectra confirms that the disc is H and He depleted, but mainly composed of C and O.
