Switching neutrino flavor flipped some dying stars from explosion to collapse in study of 195 simulations

Niels Bohr Institute astrophysicists ran 195 collapsing-star models and found neutrino flavor conversion flips the outcome for stars of 16 to 30 solar masses. The density at which conversion begins is still an input, so the effect on supernova counts is unmeasured.

Fuzzy dark matter simulated as a 3D wave field fits a lensed quasar's image positions

Physicists at HKU and Beijing Normal University derived lensing predictions straight from a three-dimensional wave simulation. On one well-studied quasar, the image positions came out closer to the data than the models they compared against.

Venus's slow spin drags simulated moons down into the planet

Stephen Kane let hypothetical moons evolve around a Venus that turns once every 243 Earth days, and in most runs they spiralled inward and hit the planet. He says Venus needed no catastrophe to end up moonless.
