🌌 How are chemical elements created in #supernovas or #NeutronStarMergers? Accurately simulating these extreme events requires enormous computing power, forcing researchers to simplify their models.

Understanding neutron star mergers with artificial intelligence

Using a novel simulation model based on machine learning, an international research team at GSI/FAIR has succeeded in gaining a deeper understanding of element formation in stellar events such as neutron star mergers. For the first time, the scientists used deep learning with a neural network to model the energy release during r-process nucleosynthesis in hydrodynamic simulations. The results are published in the journal Physical Review D.

A strange ‘chirp’ in a brilliant stellar blast points to a #magnetar
About a billion light-years away, an extraordinary stellar explosion lit up in the night sky. The blast, detected December 12, 2024, was some 30 times the brightness of a typical #supernova, putting it in a rare group of superluminous #supernovas. Now, #astronomers believe they know what made the explosion so bright — an extreme type of star called a magnetar.
