binary star

The researchers explained that the precise physical interactions that occur during the merger can impact the types of signals that could be observed on Earth from binary star mergers.

Their study of an unusual binary star system has resulted in convincing evidence that massive stars can completely collapse and become black holes without a supernova explosion.

It is estimated that up to 85% of stars exist in binary star systems, some even in systems with three or more stars.

According to the study's authors, there are more climate-friendly planets in binary star systems -- in other words, those with two suns -- than previously known.

It was just like when a binary star—two stars going around the same point—grows farther apart.
