Recalculated Orbits Of Binaries and New Linear Solutions

In this paper we present recalculated orbital elements for nine binaries: EGG 2Aa, Ab, COU 1085, COU 1897, COU 1006, A 578Aa, Ab, A 1400, A 606, BU 984, and BU 992. Seven binaries have orbital periods longer than 100 yr, and two binaries have shorter orbital periods, 38 and 76 yr. Also, we present linear solutions determined for three double stars: COU 966, J838, and A 1247. In addition to the orbital elements for nine binaries, we give absolute magnitudes, spectral types, estimates of the masses, dynamical parallaxes, and for all 12 pairs the (O - C) residuals in theta and rho.
