From Spaghetti to Lasagna: Mapping the Shapes of Nuclear Pasta

What is it about?

Inside neutron stars, the matter is squeezed so hard that the tiny cores of atoms (nuclei) stop being round and start merging with one another in wild shapes that look like pasta—spaghetti, lasagna, or gnocchi. To understand these shapes, scientists need to measure their curves and holes, kind of like telling the difference between a ball and a donut. Old methods made the shapes look blocky, like building with Legos, but a new method called alpha shapes draws them more smoothly and accurately. This helps us better understand how nuclear pasta changes with density, giving us new clues about what’s happening deep inside neutron stars.

Why is it important?

This article is important because it gives scientists a better way to measure and describe the strange “pasta” shapes that nuclear matter forms inside neutron stars. These shapes affect how heat and particles move around in a star, which in turn influences things like how neutron stars cool down or how they behave after a collision. By using a more accurate method, scientists can build a clearer picture of what’s happening deep inside these extreme objects—something we can’t see directly with telescopes.
