Abstract

Recent Hα spectroscopy of the helium-strong star δ Ori C (= HD 36485) has revealed the presence of double-peaked Hα emission in this sharp-lined and strongly magnetic B3V star. Changes in the emission are evident over a 3.5 hr time span, and the profile variations are periodic with a period on the order of 1 d. 5
