Researchers from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences and their collaborators have recently made great progress in the study of the stellar beta-decay rate of 59 Fe ...

A simulation of a rapidly accreting white dwarf showing a proposed site for the intermediate (i) process and the Summing NaI (SuN) detector. The research studied the 139Ba+n reaction, constrained by ...

The National Academies of Sciences, Engineering, and Medicine are private, nonprofit institutions that provide expert advice on some of the most pressing challenges facing the nation and world. Our ...

One of the great ongoing challenges of astrophysics, to find out how stars evolve and die, is to be tackled in an ambitious European research programme. This will involve studying in the laboratory ...

Astronomers using the James Webb Space Telescope (JWST) have made a groundbreaking discovery that could validate long-held assumptions about the early universe. The discovery, detailed in a recent ...

Astronomers don’t often get to witness a gigantic star getting undressed. But that is exactly what they witnessed with SN2021yfj, a 2.2-billion-light-year-away stellar explosion whose naked look has ...

Our understanding of the universe begins with the Big Bang, a moment in time where the universe began expanding into what we see around us now. Big Bang nucleosynthesis describes how only the lightest ...

Which stars form which elements, and how those elements form, is what stellar evolution and nucleosynthesis aims to understand. Stellar evolution looks at how stars change their structure and ...
