python\n\n[![image](http://img.shields.io/pypi/v/kimmy.svg)](https://pypi.python.org/pypi/kimmy/)\n[![Binder](http://mybinder.org/badge.svg)](https://mybinder.org/v2/gh/jobovy/kimmy/main)\n\n## Overview\n\n``kimmy`` contains simple tools to study chemical evolution in galaxies.\n\n## Author\n\nJo Bovy (University of Toronto): bovy - at - astro - dot - utoronto - dot - ca\n\n## Installation\n\nInstall the latest release with ``pip``\n```\npip install kimmy\n```\nor install the latest version by cloning/forking/downloading the repository and installing using\n```\nsudo python setup.py install\n```\nor locally using\n```\npython setup.py install --user\n```\n\n## Usage\n\nFor an example of usage, see the [example notebook](kimmy-example.ipynb). You can also launch a [Binder](https://mybinder.org/v2/gh/jobovy/kimmy/main) instance and directly play around with this notebook. _Or_ you can use [this](kimmy-example-pyodide.ipynb) [pyodide](https://github.com/pyodide/pyodide)-compatible version of the same notebook in [JupyterLite](https://github.com/jupyterlite/jupyterlite).\n\nCurrently, the only implemented feature is a simple one-zone chemical model with two elements ``O`` (for oxygen) and ``Fe`` (for iron). Initialize this model as\n```\nimport kimmy\noz= kimmy.OneZone()\n```\nthen for example compute the evolution of the default model and plot the [O/Fe] vs. [Fe/H] sequence\n```\nts= numpy.linspace(0.001,10.,1001)*u.Gyr\nplot(oz.Fe_H(ts),oz.O_Fe(ts))\n```\nTo compute the distribution of [Fe/H], do for example,\n```\nFeHs= numpy.linspace(-1.525,1.225,56)\nFeH_dist= [oz.Fe_H_DF(f) for f in FeHs]\n```\nand similar for the distribution of [O/H] and [O/Fe]. You can directly update the main parameters of the model and the model will be re-computed. For example, to set the outflow mass-loading parameter to one and plot the [O/Fe] vs. [Fe/H] sequence, do\n```\nts= numpy.linspace(0.001,10.,1001)*u.Gyr\noz.eta= 1.\nplot(oz.Fe_H(ts),oz.O_Fe(ts))\n```\nKeep in mind that once you change a parameter, it remains changed in the model. If you want to go back to the initial set of parameters that you used to initialize the instance, use ``oz.initial()``; if you want to go back to the default set of parameters, use ``oz.default()``. If you want to print the model you are using at any time, do\n```\nprint(oz)\n```\nwhich prints a nicely formatted list of all of the model parameters.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjobovy%2Fkimmy","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjobovy%2Fkimmy","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjobovy%2Fkimmy/lists"}
