UrduResearchers are combining experimental, theoretical, and observational data on neutron stars to constrain the equation of state (EOS) and to glean the composition of their interiors. Different techniques probe the EOS at different densities, thereby creating a “density ladder” that aims to connect the various rungs. The findings indicate a possible phase transition in the interior of neutron stars.

Scientists Measure Calcium Nuclei’s Thin Skin
Scientists measuring the nucleus of calcium-48 to determine how its 20 protons and 28 neutrons are distributed inside its nucleus found that the protons and neutrons aren’t simply sprinkled throughout the nucleus. Instead, they form a neutron-rich “thin skin” around a core of evenly distributed protons and neutrons. This skin is thinner than many theoretical models predicted and not consistent with expectations based on recent observations of lead’s thick skin.
