An equation of state for dense nuclear matter such as neutron stars (phys.org)
For the first time, researchers have used lattice quantum chromodynamics to study the interior of neutron stars, obtaining a new maximum bound for the speed of sound inside the star and a better understanding of how pressure, temperature and other properties there relate to one another.

JWST shocks the world with colliding neutron star discovery (bigthink.com)
Where do the heaviest elements in the Universe come from? If you were like most astrophysicists during the 20th century, you might’ve said from supernova explosions: stellar cataclysms that occur either within the cores of massive stars or from stellar corpses (white dwarfs) that undergo destructive, energy-releasing events that trigger a rapid succession of nuclear fusion reactions.

Astronomers discover neutron star with an incredibly slow six-hour spin (abc.net.au)
In our galaxy, about 13,000 light-years away, a dead star called ASKAP J1839-075 is breaking all the rules … extremely slowly.

Neutron Stars with Less Mass Than a White Dwarf Might Exist (universetoday.com)
Most of the neutron stars we know of have a mass between 1.4 and 2.0 Suns. The upper limit makes sense, since, beyond about two solar masses, a neutron star would collapse to become a black hole. The lower limit also makes sense given the mass of white dwarfs. While neutron stars defy gravitational collapse thanks to the pressure between neutrons, white dwarfs defy gravity thanks to electron pressure.

Astronomers discover one of the fastest-spinning stars in the universe (phys.org)
A new study by DTU Space researchers has revealed a neutron star that rotates around its axis at an extremely high speed. It spins 716 times per second, making it one of the fastest-spinning objects ever observed.
