Have you ever wondered what is there inside a star? Obviously it is very hard to get in there and give a look... We are therefore constrained to indirect observation that we must match with some theoretical description we have in mind.

This task is extremely challenging. The properties of the nucleon-nucleon interaction (acting on the scale of a few fm) must be exploited to explain why there are no observations of compact stars with masses larger than 1.4 solar masses, or to understand the properties of the stars cooling.

What we need is

  1. 1)a very accurate knowledge of the nucleon nucleon interaction;

  2. 2)a very accurate method to compute the properties of extensive nucleon systems.

Our approach is based on Quantum Monte Carlo techniques, i.e. stochastic methods that allow for solving almost exalctly the many-body Schroedinger equation.
