squishyplanet

Spec sheet

Purpose

A lightweight Python package for producing lightcurves and phase curves of non-spherical exoplanets.Read 5 Oct 2026 · squishyplanet.readthedocs.io

Audience

The package is aimed at users modeling non-spherical exoplanet transits and related light curves, including researchers analyzing high-precision data.Read 5 Oct 2026 · squishyplanet.readthedocs.io

Support

The maintainers ask users to report problems as GitHub issues and welcome questions to the maintainers.Read 5 Oct 2026 · squishyplanet.readthedocs.io

Exposure correction

Lightcurves can be oversampled and integrated to account for finite exposure times.Read 5 Oct 2026 · squishyplanet.readthedocs.io

GPU limit

Although it can run on GPUs or TPUs through JAX, it is not optimized for GPU use and may perform poorly there.Read 5 Oct 2026 · squishyplanet.readthedocs.io

Installation

The package installs with pip on Mac and Linux; Windows installation may require setting up compatible JAX and jaxlib versions first.Read 5 Oct 2026 · squishyplanet.readthedocs.io

Integration

The package is built on JAX and returns JAX arrays; its documentation links to jaxoplanet and starry for comparisons or implementation context.Read 5 Oct 2026 · squishyplanet.readthedocs.io

Limb darkening

It supports polynomial stellar limb-darkening profiles at arbitrary order, with coefficients supplied by the user.Read 5 Oct 2026 · squishyplanet.readthedocs.io

Modeling

It models triaxial exoplanets deformed by rotation or tidal forces and generates models for users to compare with data.Read 5 Oct 2026 · squishyplanet.readthedocs.io

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.Read 5 Oct 2026 · squishyplanet.readthedocs.io

Primary interface

The OblateSystem class generates transit, eclipse, and phase curve models for oblate planets.Read 5 Oct 2026 · squishyplanet.readthedocs.io
