Simultaneous spectroscopy and photometry of the AM Herculis-like star H0139-68

Publications of the Astronomical Society of the Pacific, 1983
We obtained one orbital cycle of spectroscopic and photometric data for the newly discovered AM Herculis-like object H0139-68. The light curve shows a flat-bottomed minimum and a flat-topped maximum, with decreasing amplitude toward shorter wavelengths. The spectrum shows strong emission lines of H, He I, and He II.
