This is a fully interactive, easy-to-use, online tool for constructing accurate non-rotating relativistic star models. With a rich collection of realistic neutron star equations of state1 as well as a polytropic approximation option, one can effortlessly explore and visualize the individual effects of central density and different matter configurations, on the internal structure and macroscopic properties of a relativistic star.
The TOV solver is implemented in C++, and compiled with Emscripten2 into WebAssembly code, which is then in-lined into a ES6 JavaScript module3. The final project was bootstrapped with Create React App.
