Astronomers Unveil Record-Breaking Fast-Spinning Neutron Star

Astronomers have discovered a neutron star in the binary system 4U 1820-30 that spins at a record-breaking 716 times per second, making it one of the fastest-spinning cosmic bodies ever observed. This neutron star, located in the globular cluster NGC 6624 in the Milky Way, also experiences powerful thermonuclear explosions on its surface. The discovery was made using NASA's NICER X-ray telescope on the ISS, and the findings provide insights into the extreme properties of neutron stars and the dynamics of binary star systems.

"Simulated Thermonuclear Explosion Achieved in Supercomputer Experiment"

Scientists are using supercomputer simulations to study the behavior of neutron stars and the thermonuclear explosions that occur when they accumulate material from a companion star. By replicating observed X-ray flares, researchers are gaining insights into the properties of neutron stars and the extreme densities within them. Using the Summit supercomputer, they have scaled their simulations to a third dimension, revealing similarities and differences between 2D and 3D models. This work provides valuable information about how neutron stars produce powerful eruptions and can help to better understand their behavior.
