The spectrum and intrinsic color of the extreme P Cyni-type star HDE 316285.
Abstract
In a high-resolution, low-noise, yellow - red CCD spectrum of HDE 316285, P Cygni profiles in Hα, He I λλ5876 and 6678, the Na D lines, and lines of N II, Si II, and Fe II are observed. In addition, [N II], Mg I, and Fe III are observed in emission. Also present is a rich array of diffuse interstellar bands, and their strengths are used to estimate the star's B-V color excess, which is found to be probably not larger than 1.5.
