jaxoplanet is a functional-programming-forward implementation of many features from the exoplanet and starry packages built on top of JAX (ascl:2111.002). It includes fast and robust implementations of many exoplanet-specific operations, including solving Kepler’s equation, and computing limb-darkened light curves. jaxoplanet has first-class support for hardware acceleration using GPUs and TPUs, and integrates seamlessly with modeling tools such as NumPyro (ascl:2505.005) and Flax (ascl:2504.026).

nuance uses linear models and Gaussian processes to simultaneously search for planetary transits while modeling correlated noises (e.g., stellar variability). The code computes the likelihood of a transit being present in some correlated noise without disentangling the two; it searches the transit signal while simultaneously modeling correlated noise, assuming that the light curve can be modeled as a Gaussian process. nuance detects single or periodic transits and can find transits in light curves from multiple instruments, whether space-based or ground-based; it can also run in parallel on CPUs or GPUs.

prose provides pipelines for performing common tasks, such as automated calibration, reduction and photometry, and makes building custom pipelines easy. The prose framework is instrument-agnostic and makes constructing pipelines easy. It offers a wide range of implemented building blocks and also allows users to define their own.
