Python package to solve Tolman-Oppenheimer-Volkoff equation. Allows to study properties of static neutron stars with given equation of state. Additionally is able to calculate tidal properties of neutron stars. The package can become quite handy by using from jupyter noebook.

To install use:

pip3 install .

Or if you do not have root access, then to install locally:

pip3 install . --user

See an example jupyter notebook in the example folder.

Solves TOV equation, calculates mass and radius of static neutron star at given central density. Calculates tidal properties of neutron star.
