An international group of astronomers conducted SGR 1830-0645 magnetary surveillance using the NiCer (Neutron Star Interior Composition Explorer) on board the ISS. Preliminary results of the study are published in the repository of preprints ARXIV.
SGR 1830-0645 was found on October 1020, when NASA SWIFT spacecraft recorded a short gamma splash from the side of the galactic plane. Subsequent observations of the outbreak showed that there was a previously unknown source of X-ray radiation. With a further study, the researchers revealed pulsations with a period of 10.4 seconds, a slowdown speed of about 0.09 picerca per second, as well as numerous short X-ray bursts. This indicates that SGR 1830-0645 is a magnetime. More detailed observations with Nicer showed that the magnetary pulse profile at the beginning of the flash has a complex morphology with three well-pronounced peaks. Scientists clarified the speed of rotation, which was approximately 0.096 Hertz, and a slowdown speed of 0.062 picercier per second. Thus, the magnetant has the tension of the dipole field at the equator at the level of 270 trillion Gauss. The age of the object reaches 24.4 thousand years, and the loss of rotation energy is 0.24 ERG decillion per second.
Magnortary are a type of neutron stars with an extremely strong magnetic field, which is more than quadrillion times stronger than the magnetic field of the Earth.
