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.
