University of New York University’s scientists in Stone Brooke reproduced an X-ray flash on a neutron star using the Summit IBM AC922 Supercompute Summit IBM AC922 Supercomputer National Laboratory. Such catastrophic explosions occur when the gravitational field of the neutron star attracts a large amount of substance from the usual star, located nearby. The results of the study published in the Astrophysical Journal magazine are available in a press release on PHYS.ORG.
When creating a model of astrophysics, various characteristics of the neutron star were varied, including the surface temperature and the speed of rotation of the object to trace how these properties affect the X-ray flash. The flash itself was presented in two-dimensional form, and scientists could observe its propagation over the surface of the neutron star.
at low speed speeds rarely occur, however, at higher, thermonuclear combustion is enhanced and remains stable due to the Coriolis force. The high temperature of the neutron star cortex speeds up the spread of the flame in the atmosphere. If the temperature is too high, the entire atmosphere is on.
In general, the simulation makes it possible to determine the exact radius of the neutron star according to the characteristics affecting the flash. According to the authors of the work, knowledge of the radius is crucial for the study of the physics of the bowels of these objects, where exotic forms of matter are present.
