$\texttt{pySYD}$: Automated measurements of global asteroseismic parameters

TL;DR

pySYD is an open-source Python tool that automates the detection of solar-like oscillations and measures global asteroseismic parameters, enhancing accessibility and reproducibility in stellar analysis for the astronomy community.

Contribution

It adapts the well-tested IDL-based SYD pipeline into Python with improvements, making asteroseismic analysis more accessible and reproducible for current and future missions.

Findings

Benchmarking shows pySYD matches closed-source tools.

Open-source nature facilitates reproducibility.

Ready for TESS mission data analysis.

Abstract

Asteroseismology is well-established in astronomy as the gold standard for determining precise and accurate fundamental stellar properties like masses, radii, and ages. Several tools have been developed for asteroseismic analyses but many of them are closed-source and therefore not accessible to the general astronomy community. Here we present $\texttt{pySYD}$, a Python package for detecting solar-like oscillations and measuring global asteroseismic parameters. $\texttt{pySYD}$ was adapted from the IDL-based $\texttt{SYD}$ pipeline, which was extensively used to measure asteroseismic parameters for $\textit{Kepler}$ stars. $\texttt{pySYD}$ was developed using the same well-tested methodology and comes with several new improvements to provide accessible and reproducible results. Well-documented, open-source asteroseismology software that has been benchmarked against closed-source tools are critical to ensure the reproducibility of legacy results from the $\textit{Kepler}$ mission. Moreover, $\texttt{pySYD}$ will also be a promising tool for the broader astronomy community to analyze current and forthcoming data from the NASA TESS mission.
