Session 22 - Binary Stars: New Generation Modeling Developments & Results.
Oral session, Tuesday, June 10
North Main Hall F/G,
The advances in the modeling of eclipsing binary light curves (generically including polarimetric, spectrophotometric, and radial velocity curves, spectral line profiles, spectral indices, and other observables) were last reviewed comprehensively in 1991 at IAU sessions in Argentina. The field has continued to develop, and since light curve models and codes are depended on to produce reliable radii and masses, among other fundamental stellar properties, it is appropriate to review what is new in both models and the programs to implement them.
The new model improvements include more realistic spot simulations, radiative transfer treatment of eclipses by translucent atmospheric clouds, improved radiation interactions between the components, non-linear limb-darkening, and non-solar metallicities. Codes are now available with improved integration and convergence techniques, and are modularized to permit added operations. The session is designed to illustrate these advances and the benefits for binary star research.
This special session is made possible by grants to EFM from NSERC of Canada, the University of Calgary's Research Grants Committee, Research Services, Faculty of Science, and the Department of Physics amp; Astronomy, all of which are appreciated.
