Abstract

A radial velocity study of the AM Herculis-type X-ray binary 2A 0311-227 was performed. Phase-dependent changes in profile were observed; the line bases have K = 430 km/s and the peaks have K = 240 km/s. The peaks have a phase lag of 25 deg relative to the bases, and the Balmer lines exhibit drastic changes in strength through the cycle in the sense that they are weak for large velocity displacements of the lines. It is suggested that the emission lines may arise from material in a magnetic funnel dropping onto the magnetic pole of a white dwarf.
