摘要：
Evidence is presented for the existence of a 2.3 day periodicity in the line-profile changes of the apparently single Wolf-Rayet star WR 134. This cyclical variability may be induced either by the presence of an orbiting collapsed companion, or by the rotational modulation of a largely inhomogeneous outflow.
