Abstract:
A new radial velocity study has been made of the highly eccentric, early-type binary BD - 1 deg 1004 using spectra from the Kavalur Observatory. All available archival material has also been reexamined. An attempt has been made to corrrect for line 'dragging' by the secondary spectrum to improve the fit of the observed data to the orbital solutions. It is found that an earlier suggestion of apsidal regression is still possible although omega is probably constant within the errors. There remain problems and inconsistencies with other orbital elements, in particular K1 and gamma.
