Elements of surprise: neutron stars contribute little, but something’s making gold, research finds

Colliding neutron stars were touted as the main source of some of the heaviest elements in the Periodic Table. Now, not so much

Neutron star collisions do not create the quantity of chemical elements previously assumed, a new analysis of galaxy evolution finds.

The research also reveals that current models can’t explain the amount of gold in the cosmos – creating an astronomical mystery.

The work has produced a new-look Periodic Table, showing the stellar origins of naturally occurring elements from carbon to uranium.

Anaemic star carries the mark of its ancient ancestor

Australian-led astronomers find the most iron-poor star in the Galaxy, hinting at the nature of the first stars in the Universe.

A newly discovered ancient star containing a record-low amount of iron carries evidence of a class of even older stars, long hypothesised but assumed to have vanished.

In a paper published in the journal Monthly Notices of the Royal Astronomical Society: Letters, researchers led by Dr Thomas Nordlander of the ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) confirm the existence of an ultra-metal-poor red giant star, located in the halo of the Milky Way, on the other side of the Galaxy about 35,000 light-years from Earth.
