vice 1.1.0

Galactic Chemical Evolution Integrator

VICE: Versatile Integrator for Chemical Evolution

Provides

• A dataframe object meant for case-insensitive lookup

• Simulations of galactic chemical evolution models

• Simulations of nucleosynthesis from single stellar populations

• Built-in yield tables from nucleosynthesis studies

How to Access the Documentation:

Documentation is available in several forms:

1. Online: http://vice-astro.readthedocs.io

2. In PDF format, available for download at the same address

3. In the docstrings embedded within the software

Running vice --docs from the terminal will open the online documentation in the default web browser.

First time users should go through VICE’s QuickStartTutorial jupyter notebook, available under examples/ in the git repository. This can be launched from the command line by running vice --tutorial.

Example scripts can be found under examples/ in the git repository at http://github.com/giganano/VICE.

Contents
