Progress report: Precise measurements of radial velocities of far-ultraviolet emission lines in stars of late spectral type
Recent high-dispersion, far-ultraviolet IUE spectra of the G-type supergiant β Draconis contain evidence for organized, persistent downflows of gas, apparently confined to a high-density component of the stellar transition zone.
