Minimum projection in eccentric binary orbits.
Abstract
The minimum projected distance of the components of a binary system is calculated for any eccentricity. The idea that minimum projected distances should occur at conjunction, irrespective of eccentricity, is incorrect. A new recursive method for computing the minimum projected separation for arbitrary periastron distance has been devised and is applied to the high eccentric orbit of the binary pulsar PSR 1913 + 16.
