VizieR Online Data Catalog: Optical spectrum of HD50975 (Sperauskas+, 2014)
Abstract
The spectrum of the hot secondary star dominates the composite spectrum of HD50975 in the far ultraviolet spectral region. Low-dispersion spectra observed by SWP and LWR cameras (SWP 04082 and LWR03613) are available for HD50975 in the IUE archive. We used IUE NEWSIPS data recalibrated by Massa & Fitzpatrick (2000ApJS..126..517M) in order to minimize systematic errors. To avoid the 2200Å interstellar extinction bump and the possible influence of primary star HD50975A we employed only spectra observed by SWP camera. In addition, spectra of four comparison stars of spectral types between B1 and B4 were extracted from the database.
