We derive analytic, closed form, numerically stable solutions for the total flux received from a spherical planet, moon or star during an occultation if the specific intensity map of the body is expressed as a sum of spherical harmonics. Our expressions are valid to arbitrary degree and may be computed recursively for speed. The formalism we develop here applies to the computation of stellar transit light curves, planetary secondary eclipse light curves, and planet-planet/planet-moon… Expand
Analytic Planetary Transit Light Curves and Derivatives for Stars with Polynomial Limb Darkening
We derive analytic, closed-form solutions for the light curve of a planet transiting a star with a limb darkening profile which is a polynomial function of the stellar elevation, up to arbitraryExpand
Analytic solutions to the maximum and average exoplanet transit depth for common stellar limb darkening laws
Context. The depth of an exoplanetary transit in the light curve of a distant star is commonly approximated as the squared planet-to-star radius ratio, (Rp/Rs)2. Stellar limb darkening, however, canExpand
catwoman: A transit modelling Python package for asymmetric light curves
TLDR
Being able to model these asymmetric signatures directly from transit light curves could give an unprecedented glimpse into planetary 3-dimensional structure, helping constrain models of atmospheric evolution, structure and composition. Expand

Eigenspectra: a framework for identifying spectra from 3D eclipse mapping
Planetary atmospheres are inherently 3D objects that can have strong gradients in latitude, longitude, and altitude. Secondary eclipse mapping is a powerful way to map the 3D distribution of theExpand
The Young Planet DS Tuc Ab Has a Low Obliquity
The abundance of short-period planetary systems with high orbital obliquities relative to the spin of their host stars is often taken as evidence that scattering processes play important roles in theExpand

TLDR
It is shown that ensembles of light curves of stars in young clusters can be used to constrain their spot distributions and marginalize over the unknown inclinations of the individual stars if the authors model their light curves as a population. Expand
