REFLUX - SIM Binary Simulator
REFLUX is a program that utilizes the Eclipsing Light Curve (ELC) code (Orosz, J.A., & Hauschildt, P.H. 2000, A&A, 364, 265) to model the flux-weighted astrometric reflex motion of a binary system with the specified parameters. Input the parameters of your system below, hit submit, and the program will generate plots of the center of light reflex orbital motion, x and y componenets versus orbital phase, the spectral energy distibution for each object and the system, as well as 3D model animation of your system, (examples on right for SS Cyg). A file that contains descriptions for all the files is also included.
ELC's convention is that star 1 is closest to the observer at phase 0.0. Thus, for sufficiently high inclinations, star 2 would be eclipsed at phase 0.0. Star 2 is typically the higher mass object. If a disk is present, it goes around star 2. Thus in CV systems, star 1 is usually the red dwarf, and star 2 the white dwarf / black hole / compact object.
If you have any questions, run into any problems, or have suggestions for improvement, please contact me at jlcough@nmsu.edu. This seems to work best with FireFox web browser. If you use Safari or IE, it is possible that you will not get a % complete dialog, however, the program will still work, and the results will still pop up eventually - just be patient, or use Firefox. Also note that model atmospheres are only available for main-sequence and giant stars - do not use on disks or compact objects or the code may choke. (In this case, or others such as accidently setting the inner disk radius bigger than the outer, the program will still run, but your resutls will all be values of 0 or nan.)
The default values below are for the SS Cyg system.
