Abstract
First orbits are derived for 12 new Hipparcos binary systems based on the precise speckle interferometric measurements of the relative positions of the components. The orbital periods of the pairs are between 5.9 and 29.0 yrs. Magnitude differences obtained from differential speckle photometry allow us to estimate the absolute magnitudes and spectral types of individual stars and to compare their position on the mass-magnitude diagram with the theoretical curves. The spectral types of the new orbiting pairs range from late F to early M. Their mass-sums are determined with a relative accuracy of 10-30%. The mass errors are completely defined by the errors of Hipparcos parallaxes.
