Researchers have recently discovered a particle with a unique isotopic composition of magnesium, indicating its origin from a supernova. The discovery was made by Dr. Nicole Neville during her doctoral work at the University of Kertin, and she now collaborates with the Institute of Lunar and Planetary Science and NASA’s Johnson Space Center.
These particles, known as pre-solar grains, are remnants from stars that existed before our Sun. They provide valuable insights into the history of these ancient stars and their composition.
Dr. Neville utilized atomic and zonal tomography techniques to analyze the particle, allowing her to determine its chemical composition at the atomic level. According to her, these particles act as time capsules, offering a glimpse into the lives of the stars from which they originated.
The isotopic ratio of magnesium in this particular particle is significantly different from anything observed in our solar system. Dr. Neville highlights that the ratio of 3025 in this particle surpasses any previous observations, which were around 1200.
Dr. David Saksi, a co-author of the study from the John de Leiter Center at the University of Kertin, emphasizes that this research expands our understanding of the Universe and pushes the boundaries of analytical methods and astrophysical models. The use of atomic and zonal tomography provided unprecedented details.
Professor Phil Bland from the University of Kertin’s School of Earth and Planetary Sciences underscores the significance of these findings in deepening our understanding of cosmic phenomena beyond our solar system. He commends the meticulous measurements at the atomic level conducted in the laboratory to unveil this new type of star.
