'The emission and absorption lines (3716-4290 Å) in the spectrum of the quasar 0237-233 are identified within the framework of the PLS model. The available evidence indicates that it is a helium star. Similarities between the spectral properties of 0237-233 and the star Upsilon Sagittarii are pointed out. Predictions are made for the absorption-line spectrum which falls outside 3716-4290 Å and also for an expected discontinuity at 2600 Å.
