Long-term variation in the short-period binary system WR46 (WN3P+?)
Published online by Cambridge University Press: 25 May 2016
Abstract
We studied the short-period (P ≈ 6–8 hr) binary system WR46 using simultaneous photometry and spectroscopy. We show that the long-term photometric variation is accompanied by changes in the equivalent width of the He II Λ5411 emission line and by an apparent period decrease on the rising branch. Furthermore, the brightening of the object is repeating.
