A new paper suggests the early solar system was shielded from the destructive force of a dying star.
, the researchers explained that they found varying concentrations of a radioactive isotope of aluminum in their meteorite samples. This showed that roughly 4.6 billion years ago, a significant amount of this substance entered the region that went on to become the solar system we know today.
The most logical explanation for this sudden abundance of radioactive aluminum, the researchers explain, is a nearby. However, for it to have delivered such a relatively large amount of the isotope, it would have been close enough to rip the early solar system apart. This suggests that the early solar system likely survived a supernova blast, according to the researchers. So how did our solar system not get obliterated by the shockwave of a nearby dying star? It was likely protected by dense filaments, or tendrils, of gas responsible for the formation of the early Sun.The scientists calculated that it would take roughly 300,000 years for the supernova from the nearby star to break up the dense filament of gas shielding our solar system.
The meteorites containing the radioactive isotopes likely broke off larger asteroids that were born in the first 100,000 years of the solar system – while it was still cocooned within this dense filament. The researchers believe their findings could help us better understand the early formation and evolution of distant star systems, as well as our own. "This scenario may have multiple important implications in our understanding of the formation, evolution, and properties of stellar systems," they stated in their paper.
