Binary Stars

My main research interests include the structure and evolution of close binary stars and the modeling of binary star observable data.

Ever since my postdoc days at the University of Florida in the 1980s, I have collaborated with Bob Wilson on many of the updates of the Wilson-Devinney binary star modeling program. The most recent (2013) public version of the program including documentation can be accessed from the FTP site ftp://ftp.astro.ufl.edu/pub/wilson/lcdc2015.  Click here for the updated documentation booklet in PDF format.

Auxiliary data files that are needed to run the programs are accessible from the pages LCDC2015 and Limb Darkening on this site.

Andrej Prsa’s binary star program Phoebe (Physics of Eclipsing Binaries) uses Wilson-Devinney as the underlying computational model, but with a very nice and user-friendly graphical interface.
