Magnetar Flares: New Clue in Cosmic Gold Formation Mystery
April 30, 2025
Researchers intend to delve into archival data to gain deeper insights into the processes that lead to heavy element creation in magnetars.
A recent study indicates that magnetar flares, which are powerful bursts of energy from highly magnetized neutron stars, may play a crucial role in the formation of gold and other heavy elements in the universe.
NASA's upcoming Compton Spectrometer and Imager (COSI) mission, scheduled for launch in 2027, aims to study magnetar flares and identify the individual elements produced in these cosmic events.
Supporting data from NASA's RHESSI and Wind missions has reinforced the conclusion that magnetar flares can eject neutron star material, contributing to the universe's heavy element abundance.
While neutron star mergers observed in 2017 demonstrated their potential to create gold, these events occur too late in the cosmic timeline to account for the earliest instances of gold formation.
Only three giant flares from magnetars have been detected in the Milky Way, underscoring their rarity and the necessity for further investigation.
This research underscores the link between cosmic phenomena and everyday materials, with Patel highlighting the significance of such extreme explosions for modern technology.
The last significant magnetar giant flare was recorded in 2004, producing a gamma ray signal that aligned with expectations for heavy metal production during such events.
Co-author Eric Burns emphasized that these findings help solve a long-standing mystery in astrophysics, utilizing previously overlooked observations.
Neutron stars, formed from the collapsed cores of supernovae, are incredibly dense, with just a teaspoon of their material weighing around a billion tons; magnetars are a specific type of neutron star characterized by their exceptionally strong magnetic fields.
