Study the birth of the sun

Australian experts are studying the prehistoric phase of the solar system, in an effort to understand the events that led to the birth of the planet's central star.

A group of scientists, led by Dr. Maria Lugaro and Professor Alexander Heger of Monash University (Australia), used radioactivity to determine the final time when heavy metal elements such as gold and silver , platinum, lead and rare earth elements, derived from other stars, have been added to the solar system's material storehouse.

'Using heavy metal nuclear radioactivity contained in asteroids to determine the time of their final accession, we have obtained clearer information about the prehistoric history of the solar system' , according to Lugaro.

Accordingly, experts learned that the last 1% addition of gold, silver, platinum to the solar system's material storage took place before the sun was born about 100 million years.

The last 1% comes from lead and rare earth metals added about 30 million years before that time, according to a Science report.

Tens of millions of years later, the material of the solar system entered the 'hatching' stage, during which the embryo nursery was formed, where the sun was born with other stars.
