Abstract

During the 1992–1993 observing season, WR3, 6, 16, 40, 66, 82 and 134 were monitored in fast photometry mode with time-resolution 0.005—0.01 s. Only WR6 reveals a possible period of P = 0.11 s (semi-amplitude A = 0.025 mag), which is close to the derived equilibrium period of a new-born pulsar in a binary system after the rapid phase of Roche Lobe Over-Flow from the original secondary component.
