The shell spectrum of the optical counterpart of GX 304-1 (4U 1258-61).
Abstract
A high-resolution spectrum of the shell star associated with GX 304-1 (4U 1258 -61) has been obtained. The star is of spectral type B2 Vne. It is rotating at near break-up velocity and losing mass, probably via an expanding equatorial disc ∼2-5 R* in size. A distance of 2.4 ± 0.5 kpc is derived.
