Story summary
- Stellar rotation enables elements formed by nuclear fusion to cross a barrier in red giants.
- Researchers from the University of Victoria’s Astronomy Research Centre and the University of Minnesota conducted simulations on supercomputers at the Texas Advanced Computing Centre and SciNet.
- The simulations show rotation increases mixing rates more than 100 times compared with non-rotating stars.
- The findings explain changes in surface composition, including the decline in the carbon-12-to-carbon-13 ratio.
