We discovered that the Wolf-Rayet (WR)+OB star binary , WR 104, renowned for its associated " dusty pin-wheel nebula " recently spatially resolved with infrared interferometry, exhibits strong quasi-periodic optical variations with a full amplitude of 2.7 mag. Such a large-amplitude, continuous variation has been unprecedented in a WR star. The optical quasi-period (∼241 d) is in almost perfect agreement with the interferometric period (243.5±3 d). The remarkable agreement of the dominant… CONTINUE READING
