Turkish scientists discover a defect in the rotation period of the double neutron star

Ankara (INA) – A team of physicists at the Turkish Middle East Technical University announced today that they have discovered a major defect in the period of rotation of the neutron star, which is considered one of the most dense objects in the universe, and takes its place within the system of double stars. Professor Altan Baikal, a member of the Department of Physics at the University, said: High-density stars explode after their fuel runs out, and a new celestial body is then formed. He indicated that the new celestial body may be a white dwarf, a neutron star, or a black hole. Pointing out that the neutron star is formed in this way, and that the aforementioned star is surrounded by very strong magnetic fields. He explained: The neutron star was observed for the first time in 1968, and has a diameter of about 10 km, and contains a high-flow liquid inside it. He added that they conducted research on this type of neutron star by analyzing archival data monitored by X-ray satellites at the university. He stated that, at the end of a three-year monitoring process, they found the existence of an orbital period for neutron stars called SXP 1062, and it constitutes one of the components of the double star system. He added: We discovered that the orbital period of this neutron star is 656 days, and we noticed in the timing analyzes that there was a significant defect in the center rotation period, which was 18 minutes. He pointed out that the double stars that send X-rays to space have been monitored via satellites since 1973, but for the first time a physicist team discovers a major defect in the period of rotation of the center around itself within the system of double stars. He added: This defect stems from the interaction of the star's shell with the liquid matter inside it, and we can consider it like an earthquake, but in this star a sudden defect occurs in its orbital period. He emphasized that astronomers in the world are seeking many discoveries about the neutron star. Stressing that science was not aware of a defect in the center of the neutron star. He expressed his belief that the discovered defect is specific to the star they observed, adding: The importance of this discovery stems from the fact that it allows understanding the period of rotation of the star and the dense matter inside it, because no one was able to solve their codes before. He noted that they published their study in the famous British scientific journal Monthly Notes of the Royal Astronomical Society on September 6. It is noteworthy that the neutron star is a celestial body with a medium diameter, and its mass ranges between 1.44 and 3 solar masses, and it is a type of remnant resulting from the gravitational collapse of a huge star in a type II, Ib, or Ic supernova. This star consists in particular of matter composed of neutrons, and its density is very large in its center, and it also has characteristics other than its large density, such as the magnetic field surrounding it, and its high temperature. Neutron stars are the smallest and most massive type of star known. (End) h p
