Peering into supernovae: Simulation points out how to detect a rapidly spinning stellar core
from California Institute of Technology
Each century, about two massive stars in our own galaxy explode, producing magnificent supernovae. These stellar explosions send neutrinos streaming our way and generate gravitational waves in the fabric of space-time. Here on Earth, large, sensitive neutrino and gravitational-wave detectors have the ability to detect these respective signals, which will provide information about what happens in the core of collapsing massive stars just before they explode. In a
paper appearing in Physical Review D
, Caltech astrophysicists predict an unmistakable signature of a feature of such an event: If the interior of the dying star is spinning rapidly just before it explodes, the emitted neutrino and gravitational-wave signals will oscillate together at the same frequency.
