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.
