"Exploring Neutron Star Surfaces with Supercomputer Simulations"

Astronomers are using a supercomputer to simulate the surface of neutron stars and study the X-ray bursts they emit. The simulations, conducted by a team of astrophysicists, revealed that the 2D and 3D models showed similar rates of flame spread, with the 3D model being necessary for more complex interactions. The Summit supercomputer's high-performance CPU and accelerated graphics processing unit were utilized to run the simulations, providing insights into the behavior of matter under extreme conditions and offering a glimpse into the composition of neutron stars.

"Breakthrough: Measuring the Staggering Speed of Neutron Star Jets"

A new study published in Nature has revealed that neutron star jets can travel at about one-third the speed of light, using a "cosmic speed camera" to measure their speed. The study found that X-ray bursts from thermonuclear explosions on neutron stars actually power up their jets, providing valuable information about how these powerful cosmic jets are launched. This discovery introduces a new technique for measuring neutron star jet speeds and paves the way for further research to understand how jet speed varies with different neutron star properties.

"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.

"China Launches 'Einstein Probe' to Study X-ray Bursts in Space"

China has launched the Einstein probe, equipped with instruments to detect X-ray bursts from phenomena like black holes and neutron star collisions, in a collaborative effort with the European Space Agency and the Max Planck Institute for Extraterrestrial Physics. The probe's Wide-field X-ray Telescope (WXT) and Follow-up X-ray Telescope (FXT) will scan the sky for X-ray emissions, potentially shedding light on gravitational wave events and high-energy processes in space.

Insights into Neutron Stars from Precision Mass Measurements of Nuclei

Researchers at the Institute of Modern Physics in China have used ultrasensitive mass spectrometry to measure the masses of several key nuclei with high precision, including germanium-64, which plays a decisive role in the nuclear reaction sequence that powers X-ray bursts on the surface of neutron stars. By using the new data to model X-ray bursts, the researchers set constraints on the properties of neutron stars, finding that the density of the neutron star is lower than expected and the temperature of the outer shell of the neutron star should be higher than generally believed after the X-ray burst.
