A: you can model misassociation (redshift measurements will look different)

In this #study, Professor #Dekel and his team propose a process termed "#feedbackfreestarburst" (FFB), which naturally explains the mystery. Under the unique conditions prevalent in #earlygalaxies, #gas efficiently turns into #stars without being disrupted by feedback processes. This idea is based on a time delay of more than one million years between the formation of #massivestars and their subsequent explosions as #supernovae.

#Astronomie: #Supernovae noch deutlich gefährlicher für Leben auf nahen #Planeten
Bislang galten zwei Phasen einer Supernova als besonders gefährlich für #Leben. Nun wurde eine weitere entdeckt, die ein #Massensterben auslösen kann.

Lo suggeriscono i risultati di uno studio del Danmarks Rumcenter (Danimarca) pubblicati la scorsa settimana su “Ecology and Evolution”.

Certe stelle finiscono la loro esistenza con una esplosione, che è fra i più violenti eventi del cosmo.
Secondo nuovi dati, questi eventi influenzano in modo persistente il clima e, attraverso quello, l'evoluzione della vita sul nostro pianeta.

"A persistent influence of supernovae on biodiversity
(...) Extensive studies of the fossil record have shown that the diversity of life forms has varied significantly over geological time, and a fundamental question of evolutionary biology is which processes are responsible for these variations.
The new study reveals a major surprise: The varying number of nearby exploding stars (supernovae) closely follows changes in marine genera (the taxonomic rank above species) biodiversity during the last 500 million years. "

Supernova 2007bi was observed in 2007. One of the products of this supernova was nickel-56, synthesized during the explosion. Nickel of mass three times greater than our entire sun was made. Nickel-56 is radioactive, decaying to cobalt-56, which itself decays to stable iron-56.
