stella is a Python package to create and train a neural network to identify stellar flares. Within stella, users can simulate flares as a training set, run a neural network, and feed in their own data to the neural network model. stella returns a probability at each data point that that data point is part of a flare or not. stella can also characterize the flares identified.

To install stella with pip:

pip install stella

Alternatively you can install the current development version of stella:

    git clone https://github.com/afeinstein20/stella
    cd stella
    python setup.py install
