Abstract (from CDS):

We continue the presentation of new orbits for Hipparcos binaries determined from regular speckle interferometric observations. Most of the data were collected in the period between 1998.77 and 2004.82 using the 6m BTA telescope of the Special Astrophysical Observatory in Zelenchuk. New orbits are presented for six pairs: HIP4809, HIP4849, HIP5531, HIP19206, HIP105947, and HIP114922. One of the pairs, HIP114922, has M dwarf components orbiting with a period of 19.72-yr. Two binaries, HIP4809 and HIP5531, have luminosity class IV components. The periods of the orbits range from 7.30-yr to 28.99-yr. All of the orbits can be considered definitive; however, the total mass error for the systems remains high, mainly due to Hipparcos parallax error.
