By David Yong, Australian National University and Gary Da Costa, AustralianNational University Canberra (Australia), Jul 9 (The Conversation) Until recently it was thought neutron star mergers were the only way heavy elements (heavier than Zinc) could be produced. These mergers involve the mashup of the remnants of two massive stars in a binary system.
But we know heavy elements were first produced not long after the Big Bang, when the universe was really young. Back then, not enough time had passed for neutron star mergers to have even occurred. Thus, another source was needed to explain the presence of early heavy elements in the Milky Way. ....

Ancient star death unlocks 13-billion-year space mystery

Ancient star death unlocks 13-billion-year space mystery
8 July 2021
No one s ever found this phenomenon before
In a world-first, astronomers from The Australian National University (ANU) have discovered evidence of a massive explosion that led to the destruction of a rapidly spinning, strongly-magnetized star.
The so-called magneto-rotational hypernova occurred around a billion years after the Big Bang and was 10-times more energetic than a supernova.
The breakthrough discovery, led by an international team of scientists, offers clues for why an unusually high concentration of metal elements were present in another ancient Milky Way star.
The star, SMSS J200322.54-114203.3, had higher amounts of zinc, uranium and europium, compared to the first stars in the universe which were predominantly made up of hydrogen and helium. ....
