Abstract

All of the Southern double star pairs published by Carl Rümker in 1832 may be
classified as very wide and measures have been obtained for only a small fraction of a single orbit. We attempt to find orbital elements of some Rümker doubles, and give an objective probability as to their binary status. Of the 28 pairs discovered by Rumker, we show some evidence for orbital (bound) movement for pairs RMK 4 and 8 and propose grade 5 orbits forthem.
