An overview of the MUSES cyberinfrastructure and how you can use it to describe neutron stars

At high energy, the fundamental description of matter (Quantum Chromodynamics or QCD) is currently only directly applicable to specific regimes, leaving large portions of the QCD phase diagram uncharted, especially around the regime relevant for neutron stars. To bridge different regimes, the MUSES collaboration has built a cyberinfrastructure that provides descriptions of matter based on first-principle theories and models across the multidimensional QCD phase diagram, including thermodynamics but also observables pertinent to heavy-ion collisions, astrophysics, and more. Our online platform allows users to choose different descriptions (with different parametrizations), how these are connected, and what observables they reproduce. The platform is open for everyone, and all our code is open source. In this talk, I present the first results in the zero-temperature limit generated by a collection of software modules that provides the user with neutron star equations of state from crust-to-core, together with stellar properties in and out of equilibrium.
