The Scenario Machine method to calculate evolution of binary stars is basically a Monte-Carlo method for statistical simulation of large ensembles of stellar binary systems originally used by Kornilov & Lipunov (1983) for massive binaries and developed later by Lipunov & Postnov (1987) for low-mass binaries (for the most recent review, see Lipunov, Postnov &Prokhorov, 1996 (LPP96)). The method is based on the construction of a great number of single evolutionary tracks with different initial conditions.
Although the present WWW-version of the Scenario Machine includes only the single-track constructor, it allows one to make quickly the evolutionary track of a close binary system with arbitrary initial parameters, such as nmasses of the components, orbital separation, orbital eccentricity, magnetic fields of compact stars, etc., as well as using different types of evolutionary scenarios (with different distributions of the kick velocity imparted to a newborn neutron star, high- or low-mass stellar wind loss diring main sequence evolution, etc.).
This is not the first example of the WWW representation of the stellar evolution. In 1995, the Goettingen group made available direct calculations of single stars evolution with parameters determined by the user on their WWW-server (http://www.uni-sw.gwdg.de/ jloxen/wwwgal/). In contrast, our code affords for the first time the calculation of binary evolutionary tracks.
