[ascl:2504.028] jaxoplanet: Astronomical time series analysis with JAX
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).
[ascl:2502.006] Giants: Pipeline to search for exoplanets around evolved stars
The Giants pipeline accesses TESS data, produces noise-corrected light curves, and searches for planets transiting evolved stars. Built with Lightkurve (ascl:1812.013) and written in Python, its emphasis is on finding giant planets around subgiant and RGB stars in TESS Full Frame Images (FFIs). Giants produces a one-page PDF summary for each target.
[ascl:2109.015] unpopular: Using CPM detrending to obtain TESS light curves
unpopular is an implementation of the Causal Pixel Model (CPM) de-trending method to obtain TESS Full-Frame Image (FFI) light curves. The code, written in Python, models the systematics in the light curves of individual pixels as a linear combination of light curves from many other distant pixels and removes shared flux variations. unpopular is able to preserve sector-length astrophysical signals, allowing for the extraction of multi-sector light curves from the FFI data.
