This is a summer project that I did in the summer of 2024 under Dr. Saumen Datta from TIFR. In this project, I learnt about Compact Stars and Dense Matter, equations of states of various models of a neutron star, and how to compute mass vs radius relations for various initial conditions. The models vary from simple to fairly involved. I used Newtonian equations for the models, hence they don't have actually accurate values. Although, it is not a very complicated matter to simply replace the equations with the appropriate relativistic versions.
This is a simple nuclear matter model for the neutron star. The details are in my Summer project report. The non-relativistic approximation is programmed here. The full model is programmed here.
This is a quark matter model for the neutron star. The model with massless quarks is programmed here. The model with strange quark mass is programmed here
Now it is time to show the results. To obtain the results for a range of initial pressure values, I simply ran the program for a range of pressure values, saved it to a csv file and then plotted it. This is a very trivial matter hence I have not included the program in this repository. Anyway, here are the results for the models
