Bradstreet2005 - Bradstreet2005V (Johnson V)

The B & V light curves are from Bonifazi & Guarnieri (1986) and the radial velocity curve is from Struve (1946). The solution presented (Bradstreet 2005) was modified from that given by Bonifazi & Guarnieri (1986) in that the new solution has a smaller primary, cooler secondary, and slightly reduced inclination. The new model presents a coherent model for both bandpasses using Roche geometry instead of triaxial ellipsoids.
