VizieR Online Data Catalog: Radial velocity in a Wolf-Rayet/O-star couple (Richardson+, 2021)
Abstract
The observations were taken with the Dominion Astrophysical Observatory 1.83m telescope (DAO), and had a resolution element of 1.33Å. In addition, we collected 34 more observations with the same telescope and spectrograph configuration, so that our total data set spans the years 1986-2013. The observations cover the wavelength range of 5150-6000Å, allowing for measurement of the HeII λ5411 emission feature for the WR star, and the absorption features of HeII λ5411, HeI λ5876, and OIII 5592 from the O star.
