NEOWISE-R data identifies ten new non-variable dust makers among WC stars (including three early subtypes), six new episodic dust makers, and revises the dust formation period of HD 36402 to 5.1 years.

abstract
Observations of the WC9+OB system WR 65 in the infrared show variations of its dust emission consistent with a period near 4.8~yr, suggesting formation in a colliding-wind binary (CWB) having an elliptical orbit. If we adopt the IR maximum as zero phase, the times of X-ray maximum count and minimum extinction to the hard component measured by Oskinova & Hamann fall at phases 0.4--0.5, when the separation of the WC9 and OB stars is greatest. We consider WR 65 in the context of other WC8-9+OB stars showing dust emission.

Variable dust emission by WC type Wolf-Rayet stars observed in the NEOWISE-R survey
NEOWISE-R data identifies ten new non-variable dust makers among WC stars (including three early subtypes), six new episodic dust makers, and revises the dust formation period of HD 36402 to 5.1 years.
