PBjam analyzes the oscillation spectra of solar-like oscillators. The code performs two main tasks: identifying a set of modes of interest in a spectrum of oscillations, and accurately modeling those modes to measure their frequencies. Mode identification relies on a large set of previous observations of the model parameters, which are then used to construct a prior distribution to inform the sampling. PJjam models the modes using a nested sampling or MCMC algorithm, where Lorentzian profiles are fit to each of the identified modes.

apollinaire: Helioseismic and asteroseismic peakbagging frameworks
apollinaire provides functions and a framework for helioseismic and asteroseismic instruments data managing and analysis, and includes all the tools necessary to analyze the acoustic oscillations of solar-like stars. The core of the package is the peakbagging library, which provides a full framework to extract oscillation modes parameters from solar and stellar power spectra.

kiauhoku: Stellar model grid interpolation
Kiauhoku interacts with, manipulates, and interpolates between stellar evolutionary tracks in a model grid. It was built for interacting with YREC models, but other stellar evolution model grids, including MIST, Dartmouth, and GARSTEC, are also available.

K-Inpainting: Inpainting for Kepler
Inpainting is a technique for dealing with gaps in time series data, as frequently occurs in asteroseismology data, that may generate spurious peaks in the power spectrum, thus limiting the analysis of the data. The inpainting method, based on a sparsity prior, judiciously fills in gaps in the data, preserving the asteroseismic signal as far as possible. This method can be applied both on ground and space-based data. The inpainting technique improves the oscillation modes detection and estimation, the impact of the observational window function is reduced, and the interpretation of the power spectrum is simplified. K-Inpainting can be used to study very long time series of many stars because its computation is very fast.
