A team of researchers has made a breakthrough in understanding how massive stars can create heavy elements, a process that has puzzled scientists for decades. By studying the common envelope jets supernova (CEJSN) scenario, they have found that these stars can indeed produce large amounts of heavy elements, such as gold and uranium.
The CEJSN scenario occurs when a massive star loses its outer layers, creating a dense core surrounded by an accretion disk. As this disk spins faster and faster, it heats up and begins to create heavier elements through the process of rapid neutron capture, or r-process nucleosynthesis. This process involves the absorption of neutrons by atomic nuclei, causing them to become heavier and heavier.
In their study, the researchers used complex computer simulations to model the CEJSN scenario and track the formation of heavy elements in the accretion disk. They found that the disk can be so dense that it is able to create a large number of r-process events, which are the key to producing these heavy elements.
One of the most interesting results of the study was the discovery that the CEJSN scenario can produce a wide range of heavy elements, from lighter ones like iron and nickel to heavier ones like gold and uranium. This is because the accretion disk can create different conditions for r-process nucleosynthesis, depending on factors such as its density and temperature.
The researchers also found that the CEJSN scenario can produce large amounts of these heavy elements, which could have important implications for our understanding of the origins of the universe. For example, they may have played a key role in the formation of the first stars and galaxies, or even influenced the distribution of heavy elements in the cosmos.
The study’s findings are significant because they provide new insights into the processes that create heavy elements in massive stars. This knowledge can help scientists better understand the origins of these elements and how they are distributed throughout the universe.
In addition to its scientific significance, the study also highlights the importance of continued research into the mysteries of massive stars. These stars are complex and poorly understood, but they play a crucial role in shaping our understanding of the universe.
Overall, the study’s findings have significant implications for our understanding of the origins of heavy elements and the evolution of massive stars. The discovery that these stars can create large amounts of heavy elements through the CEJSN scenario is an important step forward in our understanding of the universe.
