The Binary Pulsar: PSR 1913+16 -- Information on the PSR 1013+16 pulsar, a part of a binary system, the discoverers of which won the Nobel Prize in 1993. Visit

Astronomical League Double Star Club -- The purpose of the Double Star Club is to introduce observers to 100 of the finest double & multiple stars in the heavens. Visit

On The Mechanics of Star Formation - Binary Stars & Nemesis -- Brief scientific paper on accretion disk polar jetting by Max Domaschko, PhD, So. Charleston, WV, USA. Also links to a small page of hubble photographs of jetstreams from young stars. Visit

Mass Transfer in the Binary Star Algol -- This site shows the dynamic hydrodynamic models have shown that the circumstellar flow in Algol is relatively independent of the initial speed & direction of the tidal stream. Rather, the flow dynamics are determined primarily by the strength of radiative cooling, which depends on the density of the gas in the mass transfer stream. Visit
