Variable dust formation by the double-line spectroscopic binary WR 70 (HD 137603, WC9vd+B0I)
Infrared photometry of the WC9vd+B0I spectroscopic binary WR 70 over two decades shows variable dust emission. The variations are relatively slow and show evidence for an underlying process with a period P = 1045 ± 60 d, together with modulation on shorter and longer time-scales.
