Semi-analytic SN lightcurves
snlc calculates semi-analytic supernova lightcurves using Arnett's
approximation that the spatial and temporal structure can be
separated. It relies on NumPy, Astropy, and matplotlib.
It was created for a University of Toronto transients class, and likely contains bugs.
Installation instructions
The package and its dependencies can be installed with:
pip install git+https://github.com/mhvk/snlc.git#egg=snlc
Basic example
The following is to get a quick lightcurve with parameters like those for SN 2011fe.
>>> import numpy as np >>> import astropy.units as u >>> import matplotlib.pyplot as plt >>> from snlc.arnett import Arnett >>> from snlc.figures import SN2011fe >>> model = Arnett(**SN2011fe) >>> t = np.linspace(0, 40, 41) << u.day >>> lc = model(t) >>> plt.plot(t, lc['l'].to(u.Lsun), label='AFM17')
Do inspect the SN2011fe dict with parameters, and the output
lc! The figures.py file and the tests are useful places to
get started.
