For the first time, scientists are simulating real reactions of supernovae in a laboratory

For a few brief moments, scientists observed the explosive power of a supernova in a laboratory. Researchers from the University of Surrey in the United Kingdom are collaborating with scientists from the Canadian National Laboratory TRIUMF to perform the first direct measurement of a supernova response in a laboratory environment, press release reveals. The international team used an accelerated beam of radioactive nuclei for its experiment.

In a new study published in the journal Physical examination letters, researchers describe in detail the first time scientists have been able to measure one of the processes by which the heaviest elements in the universe are produced.

Scientists used an accelerated beam of radioactive ions to observe the processes outlined in scientific theories of supernova reactions. Their measurements shed light on the process of capturing protons, which scientists say is responsible for producing p-nuclei, isotopes that make up approximately one percent of the heavy elements observed in our solar system — although we don’t know how they originated.

The lack of isotopes of P-nuclei means that they are difficult to observe, which makes it difficult for scientists to understand how isotopes rich in protons and neutron deficient are produced. Like A warning to science points out, the theory of greatest adhesion is the gamma process in which atoms capture flying protons during an explosive event such as a supernova.

New supernova research opens up “wealth of possibilities”

The new observations from an international team of researchers were conducted in the isotope separator and accelerator II at the TRIUMF National Laboratory in Canada. The machine was used to produce a beam of charged, radioactive rubidium-83 atoms while the process was recorded in the laboratory.

Connecting a high-resolution gamma-ray array to an advanced electrostatic measuring separator gamma process reactions are a key cornerstone in the direct measurement of astrophysical processes, “said Dr. Gavin Lothay of the University of Surrey.” Such measurements were largely considered inaccessible to current experimental technologies, and the latest study has now opened up a wealth of possibilities for the future. “

In 2019, researchers from the University of Guelph and Columbia University launched a study detailing his theory that all the world’s heaviest elements, including gold and platinum, were forged into a rare form of supernova called collapse. Such research sheds light on the processes taking place in supernovae, which, in simple words, can be considered as factories of the element, as they are responsible for forging any element that is heavier than oxygen – which means that they are responsible for our existence.
