| Abstract: |
We introduce new software for the modeling of exoplanet transit light curves. The
technique is based on the aperture cross correlation between the light changes
and the diffraction pattern of the apertures representing the eclipsing binary
components (Kopal 1977; Kopal & Demircan 1978), where in the present case
the eclipsing component is considered to be a transiting exoplanet.
The software finds the best parameters including the fractional radii of the
exoplanet and the host star, the inclination and eccentricity of the orbit,
the longitude of periastron, limb-darkening coefficients of any
degree, and the transit time, yielding the lowest χ2. Parameter uncertainties
are calculated with the jackknife method. We compare results
for selected exoplanet transit light curves against those available in the
literature. |
