A package for peakbagging solar-like oscillators

Project description

Peakbagging made easy Documentation Status

PBjam is toolbox for modeling the oscillation spectra of solar-like oscillators. This involves two main parts: identifying a set of modes of interest, and accurately modeling those modes to measure their frequencies.

Currently, the mode identification is based on fitting the asymptotic relation to the l=2,0 pairs, relying on the cumulative sum of prior knowledge gained from NASA’s Kepler mission to inform the fitting process.

Modeling the modes, or ‘peakbagging’, is done using the HMC sampler from pymc3, which fits a Lorentzian to each of the identified modes, with much fewer priors than during he mode ID process. This allows for a more accurate model of the spectrum of frequencies, than the heavily parameterized models like the asymptotic relation.
