The integration between black holes and neutron stars in a dense star cluster is in stark contrast to the regions that make up the regions where stars are few. Their associated properties may be important for the study of gravitational waves and their origin. Dr. Manuel Arca Sida of the Institute for Astronomical Computing at the University of Heidelberg concluded in a study in a study that used computer simulations. This research could provide important insights into the fusion of two large stellar objects that astronomers observed in 2019. The results were published in the journal
Stars much larger than our Sun usually end their life as neutron stars or black holes. Neutron stars emit regular pulses of radiation that allow them to be identified. In August 2017, for example, when the first double neutron star integration was observed, scientists around the world detected the burst light from their binoculars. Black holes, on the other hand, are usually invisible because their gravitational pull is so strong that even light cannot escape, making them invisible to electromagnetic devices.
If two black holes meet, the phenomenon may be hidden, but it can still be detected by space-time waves in the form of so-called gravitational waves. In the United States, some detectors, such as the Laser Interferometer Gravitational Waves Observatory (LIGO), are able to detect these waves. The first successful live observation was made in 2015. This signal was created by the fusion of two black holes. But this phenomenon cannot be the only source of gravitational waves, which can also come from the fusion of two neutron stars or a neutron star in a black hole. According to Dr. Arka Seda, one of the biggest challenges is discovering the differences in observing these events.
In his research, the Heidelberg researcher analyzed the fusion of a pair of black holes and neutron stars. It used a detailed computer simulation of interactions between stars and a compact object such as a black hole system and a third large-scale roaming object required for fusion. The results show that three such physical interactions can actually contribute to black hole-neutron star integration in dense stellar regions such as global star clusters. A special family of dynamic mergers that is distinctly different from mergers in isolated areas can be defined," explains Manuel Arca Sedda.
The fusion of a black hole with a neutron star was first observed in August 2019 by gravitational-wave observatories. Yet optical observers around the world have failed to find an electromagnetic counterpart in the region where the gravitational wave was generated, suggesting that the black hole would have destroyed the neutron star without first destroying it. It was completely eaten. If confirmed, it would be the first observational black hole in a dense stellar environment. Neutron star integration can occur, as described by Dr. Arka Sida.
