Analytical transit light curves for arbitrary power-law limb darkening: a unified framework

Farrukh A. Chishtie, Mohammad I. Saeed, Shaukat N. Goderya

We present a unified analytical framework for computing exoplanet transit light curves under arbitrary real power-law limb darkening $I(\hat{I}¼)=I_0\hat{I}{¼}^{\hat{I}}\pm$, $\hat{I}\pm >-2$, eliminating the two-…
