Accessible Asteroseismology with Lightkurve

In this software demo I run through the Lightkurve package's frequency-domain analysis tools, and the new tools used to estimate rudimentary stellar and asteroseismic parameters for solar-like oscillators.

The majority of the talk was a demonstration using these tools on a Kepler Main-Sequence target in a Jupyter Notebook. An annotated version of this notebook can be found here: https://github.com/ojhall94/TASC5_lightkurve/blob/master/Notebooks/Colab-Rudy-example.ipynb, with a link to a Google Colab version.

There are also examples with K2 and TESS data, which can be found on on GitHub here: https://github.com/ojhall94/TASC5_lightkurve

Note: there are hyperlinks taking you to guides on how to collaborate and contribute to lightkurve, which are accessible if you download the slides!

   It does:
   provides accessible frequency-domain tools
   estimates stellar parameters in a transparent way
   easy quick look at seismic data
   It does not (yet?):
   provide uncertainties for parameters
   replace a pipeline (or an email to a seismologist)
