Cím: "Physical Analysis and Numerical Modeling of Eclipsing Binary Stars"

Abstract:
"Eclipsing binary stars are among most attractive objects in stellar
astrophysics. Their particular geometrical layout and well known
governing laws of dynamics and radiative physics enable a detailed and
accurate modeling and analysis of the acquired observational data.
Accuracy is crucial, because the results obtained from the model are
used by the community to obtain reliable calibrations, tests on
evolutionary sequences and distance estimates. The talk will discuss
basic modeling principles along with several important physical,
numerical and technical advancements. These include obtaining individual
temperatures objectively by means of color-constraining, imposing sets
of conditional constraints to the model, rigorous treatment of
interstellar extinction, using spectra as a native data source,
powerful heuristical minimization algorithms, a flexible scripting
facility, an intuitive graphical user interface. We will demonstrate
these features on several astrophysically challenging binaries."
