StructureSolver.jl

StructureSolver.jl is a Julia package for solving 1D (spherically symmetric) relativistic stellar structure models in Damour–Esposito–Farese (DEF) scalar-tensor gravity, with helper tools for neutron-star equations of state (EoS).

It is aimed at research workflows: single solves, parameter scans, families of models, and sensitivity/derivative extraction.
