mistery

mistery (c.f. "MIST query") is a Python module for retrieving data from the MESA Isochrones and Stellar Tracks (MIST) database of stellar models. The module allows you to fetch data by submitting requests to the web interpolator. It is intended as a lightweight teaching tool that lets students access real-world stellar model data. If you're doing intensive scientific work, you're probably better off accessing the data in other ways (e.g. by downloading packaged model grids).

To use mistery, copy the module file mistery.py to somewhere your Python interpreter will find it (e.g. your working directory or somewhere in your $PYTHON_PATH). Then fetch a single track with

    track = mistery.get_track(M=3.1081, FeH=-0.8128)

The data is returned as a structured NumPy array. i.e. you can access the columns by name rather than number. To see a list of names, use

    print(track.dtype.names)

and access columns with statements like track['log_L'].

You can download multiple tracks in one call by instead passing an iterable of masses to mistery.get_tracks, e.g.

    tracks = mistery.get_tracks(M=[1.086718, 2.8511], FeH=0.012756)

The data in tracks is now a list of tracks and can be accessed with e.g. tracks[0]['log_L'].
