Supercomputer simulations identify stellar rotation as the mechanism driving chemical mixing in red giants, explaining long-observed surface composition changes during stellar evolution.
A comet wandering through space was observed to abruptly slow its rotation, stop completely, and then begin spinning in the ...
Advances in supercomputing have made solving a long‐standing astronomical conundrum possible: How can we explain the changes in the chemical composition at the surface of red giant stars as they ...
