The VIIth catalogue of galactic PopulationI Wolf–Rayet stars provides improved coordinates,
spectral types and bv photometry of known WR stars and adds 71 new WR stars to the …

We construct revised near-infrared absolute magnitude calibrations for 126 Galactic Wolf–
Rayet (WR) stars at known distances, based in part upon recent large-scale spectroscopic …

To probe the distribution and physical characteristics of interstellar gas at temperatures
T\approx 3\times 10^{5} K in the disk of the Milky Way, we have used the Far Ultraviolet …

We summarize new X-ray detections of four nitrogen-type Wolf–Rayet (WR) stars obtained in
a limited survey aimed at establishing the X-ray properties of WN stars across their full range …

We have observed H α and [O III] emission from eight of the most well-defined Wolf-Rayet
ring nebulae in the Galaxy. We find that in many cases the outermost edge of the [O III] …

We present a morphological study of nebulae around Wolf-Rayet (WR) stars using archival
narrow-band optical and Wide-field Infrared Survey Explorer (WISE) infrared images. The …

We show radio continuum observations of the WR ring nebulae around WR 101 and WR
113 obtained using the VLA and H i 21 cm line data of the interstellar bubble around the O …

We present for the first time the detection of mid-J CO line emission in the outskirts of an
evolved massive star, which indicates the presence of warm and/or high-density molecular …

We have examined the interstellar medium in the vicinity of massive stars belonging to the
Per OB1 association based on neutral hydrogen 21 cm observations obtained with the 100 …

NGC 2359is an optical nebula excited by the powerful wind and the radiation of the Wolf-
Rayet star HD 56925. We have investigated the interaction between this massive star and …
