of Global Asteroseismic Parameters¶
pySYD is an open-source python package to detect solar-like oscillations and measure global asteroseismic parameters.
pySYD provides best-fit values and uncertainties for the following parameters:
Granulation background, including timescales and amplitudes
Frequency of maximum power
Large frequency separation
Mean oscillation amplitudes
For a basic introduction to these parameters and asteroseismic data analysis of solar-like oscillators see Bedding et al. 2014.
pySYD is a python-based implementation of the IDL-based SYD pipeline (Huber et al. 2009), which was extensively used to measure asteroseismic parameters for Kepler stars. Papers based on asteroseismic parameters measured using the
SYD pipeline include Huber et al. 2011, Chaplin et al. 2014, Serenelli et al. 2017 and Yu et al. 2018.
pySYD adapts the well-tested methodology from
SYD while also improving these existing analyses and expanding upon numerous new
(optional) features. Improvements include:
Statistical best-fit background model selection
Easily accessible + command-line friendly
Ability to save samples for further analyses
