star system

Some of it will form a cloud around the binary star system.

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.

The researchers have analysed the observational data for a range of signs that would be expected from a star system having undergone a supernova-explosion in the past.

She expects that the star system will be important for studying stellar evolution and collapse.

Similarly, the symmetry of a star system's orbit usually show signs that it has felt the impact of a violent supernova explosion, because of the ejection of matter that happens.
