The optical spectrum of the O-type subdwarf BD +28°4211.

HERBIG G.H.

Abstract (from CDS):

High-resolution spectra of the O subdwarf BD +28°4211 in the optical region show emission lines of H and He II within the absorption profile of Hα. Central emission is also present in Hβ and in the He II lines at 4686 and 5411 Å. Weaker emission lines of N V, C IV, and Si IV are also present, as are a large number of narrow absorption lines of O IV, O V, Si IV, and N IV, from which an upper limit on vsini can be estimated.
