The Wolf‐Rayet Binary WR 141 (WN5o + O5 V–III) Revisited
TL;DR: In this article, the radial velocity measurements of the spectroscopic binary WR 141 were combined with new CCD data from 1988-1989 and 1992, complemented by polarimetric broadband measurements from 1989.

Massive Binary WR 112 and Properties of Wolf-Rayet Dust
TL;DR: In this paper, the authors reported the discovery of a relatively cool, extended, multiarc dust envelope around the star WR 112, most likely formed by wind-wind collision in a long-period binary system, and derived the binary orbital parameters, the dust temperature, and the dust mass distributions in the envelope.

TL;DR: In this paper, a simple model was developed to investigate the effect of a strongly ionizing, accreting companion on the Wolf-Rayet wind structure and the expected emergent X-ray luminosity.

TL;DR: In this paper, the MOST data were used to search for acoustic (p-mode) oscillations in the star Kappa1 Ceti, with a sampling rate of approximately once per minute and a noise level around 7-9 mu_mag at frequencies in the range 0.5-4 mHz.
