Facts

Purpose
A lightweight Python package for producing lightcurves and phase curves of non-spherical exoplanets.squishyplanet.readthedocs.io · 5 Oct 2026
Modeling
It models triaxial exoplanets deformed by rotation or tidal forces and generates models for users to compare with data.squishyplanet.readthedocs.io · 5 Oct 2026
Primary interface
The OblateSystem class generates transit, eclipse, and phase curve models for oblate planets.squishyplanet.readthedocs.io · 5 Oct 2026
Limb darkening
It supports polynomial stellar limb-darkening profiles at arbitrary order, with coefficients supplied by the user.squishyplanet.readthedocs.io · 5 Oct 2026
Exposure correction
Lightcurves can be oversampled and integrated to account for finite exposure times.squishyplanet.readthedocs.io · 5 Oct 2026
Integration
The package is built on JAX and returns JAX arrays; its documentation links to jaxoplanet and starry for comparisons or implementation context.squishyplanet.readthedocs.io · 5 Oct 2026
Performance limit
The documentation estimates transit-only calculations at tens of milliseconds and phase-curve evaluations at hundreds of milliseconds, and says gradient-dependent methods such as HMC are likely impractical currently.squishyplanet.readthedocs.io · 5 Oct 2026
GPU limit
Although it can run on GPUs or TPUs through JAX, it is not optimized for GPU use and may perform poorly there.squishyplanet.readthedocs.io · 5 Oct 2026
Installation
The package installs with pip on Mac and Linux; Windows installation may require setting up compatible JAX and jaxlib versions first.squishyplanet.readthedocs.io · 5 Oct 2026
Support
The maintainers ask users to report problems as GitHub issues and welcome questions to the maintainers.squishyplanet.readthedocs.io · 5 Oct 2026
License
The project is freely available under the MIT License.github.com · 5 Oct 2026
Audience
The package is aimed at users modeling non-spherical exoplanet transits and related light curves, including researchers analyzing high-precision data.squishyplanet.readthedocs.io · 5 Oct 2026
