Improving the Light Curve Synthesis Program EBOP: Variable Position of the Periastron and Second Order Limb Darkening
EBOP is one of the most commonly used codes for the light curve synthesis of detached eclipsing binaries. We have added to the original version the possibility to analyze binaries showing fast apsidal motion by introducing a variable position of the periastron. On the other hand, we have also introduced the possibility of using non-linear limb darkening laws to reproduce the surface flux distribution. A systematic difference was found in the orbital inclinations computed with our extended version of EBOP with respect to the standard one.
