Evolutionary tracks

mistery.get_tracks(Ms=[1.0], FeH=0.0, vvcrit=0.0, Av=0.0, photometry=None)

Returns a list of evolutionary tracks from the MIST database. The script makes the PHP request, infers the archive’s filename, decompresses it, combines the theoretical and photometry data if necessary and returns a list of NumPy structured arrays. You can get the list of column names with e.g.

tracks = mistery.get_tracks(Ms=[1.0, 2.0], FeH=-0.5)
print(tracks[0].dtype.names)
Parameters

  • Ms (iterable of floats) – Masses of the desired tracks, in solar units.

  • FeH (float) – Metallicity [Fe/H] of the tracks.

  • vvcrit (float, 0.0 or 0.4 only) – ZAMS rotation rate of the tracks, relative to critical.

  • Av (float) – Extinction coefficient.

  • photometry (None or str) – Name of the table of photometric bands to include. e.g. 'UBVRIplus'. See Photometry table options for all options.

Returns

tracks – List containing the evolutionary tracks, in the same order as Ms. Always includes the 77 columns of theoretical data and also includes photometry if photometry is not None.

Return type

list of NumPy structured arrays

mistery.get_track(M=1.0, **kwargs)

Returns a single evolutionary track from the MIST database with mass M (in solar units) and other keywords options that are passed to get_tracks() (e.g. FeH). The function really just calls get_tracks() with Ms=[M] and returns a single NumPy structured array, rather than a list of them. See get_tracks() for more details.

Isochrones

mistery.get_isochrones(ts=[1.0], split=True, FeH=0.0, vvcrit=0.0, Av=0.0, theory='basic', photometry=None)

Returns a set of isochrones from the MIST database. The script makes the PHP request, infers the filename, and returns a list of NumPy structured arrays. You can get the list of column names with e.g.

isochrones = mistery.get_isochrones(ts=[0.3, 1.3], FeH=-0.25)
print(isochrones[0].dtype.names)

The data is returned in a single .iso file, which is split up into a list of arrays for each age if split=True. Otherwise, a single array is returned that contains all the isochrones.

Parameters

  • ts (iterable of floats) – Ages of the desired isochrones, in billions of years (Gyr).

  • split (bool) – If True, return a list of arrays corresponding to each age in ts, in that order. Otherwise, return the single array that the web form returns.

  • FeH (float) – Metallicity [Fe/H] of the isochrones.

  • vvcrit (float, 0.0 or 0.4 only) – ZAMS rotation rate of the isochrones, relative to critical.

  • Av (float) – Extinction coefficient.

  • theory (None, 'basic' or 'full') – How much theoretical data to include.

  • photometry (None or str) – Name of the table of photometric bands to include. e.g. 'UBVRIplus'. See Photometry table options for all options.

Returns

isochrones – If split=True, a list containing the isochrones, in the same order as ts. If split=False, a single array containing all the isochrones. Columns in the arrays depends on choice of theory and photometry.

Return type

NumPy structured array or a list of NumPy structured arrays

mistery.get_isochrone(t=1.0, **kwargs)

Returns a single isochrone from the MIST database with age t (in Gyr) and other keywords options that are passed to get_isochrones() (e.g. FeH). The function really just calls get_isochrones() with ts=[t] and returns a single NumPy structured array, rather than a list of them. See get_isochrones() for more details.

Scraped from MIST form.
