Include TOVola: An enhanced TOV solver with Tabulated EOS support

[David Boyer]

TOVola is an enhanced TOV solver that has support of multiple different EOS types (Simple and Piecewise Polytrope, and Tabulated EOS) through the use of the GRHayLib thorn. It also has access to two different ODE methods through the use of GSL’s ODE solver (RK4(5) and DP7(8)), but more methods can be added in the future if there is a desire, as long as it is a GSL compatible method.

To be used in the GRHayL announcement paper, currently in prep.
