Neutrinos May Hold Key to Supernova Mysteries
Confirmed
In Short: A new paper suggests that neutrinos changing identities could explain discrepancies in supernova models.
According to a paper in Physical Review D, the key to these discrepancies might lie in the behavior of neutrinos, which are known to change their identity or 'flavor.
Neutrinos play a crucial role in current supernova models, but their ability to switch identities has not been fully accounted for in these models.
The paper proposes that flavor-changing neutrinos could provide a missing piece in understanding how and when a neutron star collapses into a black hole.
Understanding these phenomena could help clarify whether all core collapses result in a supernova and shed light on the mysteries surrounding the transition from neutron star to black hole.

What's still developing
- The statistics of supernovae that we’ve observed indicate that the model may be seriously incomplete.
- We’ve observed plenty of supernovae, so it would seem like there would be little mystery left.
- But that data is complicated by the fact that theorists haven’t definitively identified the conditions that determine when a neutron star tips over into a black hole instead.
- Our basic understanding of core-collapse supernovae hasn’t changed in decades.
- And on the theoretical side, there are still plenty of uncertainties, including over some of the basics, such as whether all core collapses actually result in a supernova.
- It was heartbreaking then, when on August 28, 2009, right before performing at the Rock en Seine Festival in Paris, it was announced that a backstage fight between the Gallagher brothers that very moment, a result of tensions building between the two for some time now–both on-stage and off–had resulted in the breaking up of the band for good.
- Ever the rock ‘n’ roll stars, when they finally did, it was through the cinema’s entrance instead of from a car at the start of the carpet, causing screams to erupt.
- Oasis mania hit Venice Film Festival on Saturday night as Liam and Noel Gallagher presented the world premiere of their highly anticipated documentary “Don’t Look Back in Anger.” As the documentary rolled on, the rowdiness continued — attendees clapped after most of the live performances in the film and, as the audience sang along to “Champagne Supernova,” several were reduced to audible tears.
