Binary Stars

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

Astronomy 101/103 Web Simulations - Includes two JAVA simulations of binary star systems.

Binary Star Simulation - This is a representation of the binary star on a graphical and easy way.

Binary Stars Astronomy Lecture - A single introductory astronomy lecture on Binary Stars, including several useful diagrams.

The Double Star Library - A means by which various types of binary and multiple star information can be easily disseminated among binary star astronomers in IAU Commission 26 and related commissions.

Double Stars to Follow - A five-part article by Martin Gaskell of the Prairie Astronomy Club.

Eclipsing Binary Stars - Information on binary stars and links to online articles.

The Formation of Binary Stars - Recent observational investigations of the frequency of occurrence of pre-main-sequence binary stars have reinforced earlier suspicions that binary formation is the primary branch of the star-formation process

Hubble Separates Stars In The Mira Binary System - Hubble Space Telescope News Release/Paper about the discovery of the atmospheric interaction between the giant star Mira and its white dwarf companion star.

Interacting Binary Stars - Nice click-through tour with some great animations about some of the complexities of Binary Systems.

International Astronomical Union - Organization based in Hungary that studies binary stars.

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 and 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.
