| Abstract: |
AC Vel has two B-type eclipsing components, and the presence of a third component is indicated by: 1) light-time effects, and 2) the need for about ten per cent third light in the photometric solutions. The wide orbit is derived from the light-time effect and provides a surprisingly high lower limit to the mass of the third component, indicating that this component is multiple. We present the disentangling of the binary component spectra, and the identification of the third component in the Balmer hydrogen lines. |
