Scientists discover a promising way to create new superheavy elements
What is the heaviest element in the universe? Are there infinitely many elements? Where and how could superheavy elements be created naturally?
Page 5: Research news on Nuclear astrophysics
Nuclear astrophysics is a research area at the interface of nuclear physics and astrophysics that investigates how nuclear processes govern the origin, evolution, and observable properties of cosmic objects and matter. It focuses on nuclear reaction rates, decay schemes, and equation-of-state properties under astrophysical conditions, and applies them to models of stellar structure, nucleosynthesis, supernovae, compact objects, and the early universe. The field integrates laboratory measurements, theoretical nuclear structure and reaction calculations, and astronomical observations to constrain reaction networks and to interpret elemental and isotopic abundances, energy generation, and neutrino and gravitational-wave signals in astrophysical environments.
Experimental data help unravel the mystery surrounding the creation of heavy elements in stars
How are stars born, and how do they die? How do they produce the energy that keeps them burning for billions of years? How do they create the elements we observe today? Definitive answers to these questions continue to elude ...
