Graph comparing a neutron star with a quark-matter core vs. a nuclear matter core in mass vs. radius. The quark matter core star would have less mass and radius than the nuclear matter core, as stars with smaller radii and more mass are too unstable.

New Clues on Twin Neutron Stars and the Extreme Physics Inside

Scientists have new insights into factors that determine how twin neutron stars—stars with the same mass but different sizes and compositions—can coexist.

Predictive Theory Revises Understanding of Alpha Processes During the Big Bang and in Massive Stars

Theoretical calculations enable more accurate determination of reaction rates for modelling primordial lithium-6 abundance and massive stars’ lifecycle.
