Discovery of a 310-day Period from the Enshrouded Massive System NaSt1 (WR 122)
Ryan M. Lau, Samaporn Tinyanont, Matthew J. Hankins +15
We present optical and infrared (IR) light curves of NaSt1, also known as Wolf-Rayet (WR) 122, with observations from Palomar Gattini-IR (PGIR), the Zwicky Transient Facility (ZTF)…
The colliding-wind WC9+OB system WR 65 and dust formation by WR stars
P. M. Williams, K. A. van der Hucht
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 (…
Recurrent dust formation by WR 48a on a 30-year timescale
Peredur M. Williams, Karel A. van der Hucht, Francois van Wyk +4
We present infrared photometry of the WC8 Wolf-Rayet system WR 48a observed with telescopes at ESO, the SAAO and the AAT between 1982 and 2011 which show a slow decline in dust emi…
Dust formation by the colliding-wind WC5+O9 binary WR19 at periastron passage
P. M. Williams, G. Rauw, K. A. van der Hucht
We present infrared photometry of the episodic dust-making Wolf-Rayet system WR19 (LS3), tracking its fading from a third observed dust-formation episode in 2007 and strengthening…
