Abstract

A description of the relative rectilinear motion of double stars provides an important clue to the relationship of the components. The aim is to provide an objective method of obtaining Rectilinear Elements. We present a simplified method to calculate relative rectilinear motion, relying on the data obtained from the HIPPARCOS and GAIA DR1 missions, together with their uncertainties. As examples, we present the Rectilinear Elements of RMK 1, 3, 4, 5, 6, 8, 10, 11, 12, 17, 20, 25, 27, and 28.
