Table information for 'wr_wn_sequence.main'

General

This table is available for ADQL queries and through the TAP endpoint.

Resource Description: This catalogue contains results of photometric and spectral observations of 11 Galactic Wolf-Rayet stars of the WN sequence, obtained in 2021–2022 at the Fesenkov Astrophysical Institute (FAI), Kazakhstan. The programme included moderately bright stars (mostly fainter than V = 10m) observed in B, V, and Rc photometric filters, and medium-resolution spectra for measurement of absolute fluxes in prominent emission lines. For each object the table provides: identifiers (WR catalogue number, alternative name), spectral subtype, equatorial coordinates (J2000), literature photometry (B_cat, V_cat), reference codes, date of observation, measured B, V, Rc magnitudes and their errors, and absolute fluxes and equivalent widths for a set of emission lines, including He II λ4540, N III λ4619, He II λ4685, He II + H I λ4859, N V λ4945, He II λ5411, He II λ6560, He II λ6583, and N IV λ7109. Variability at the level of 0.1–0.15 mag in brightness was detected for WR 1, WR 120, WR 151, and WR 152. Changes in emission-line fluxes were found in WR 120, WR 128, and WR 145.
