Rogue Stars and Their Origins

What are rogue stars and how do they become 'homeless'?

• They are stars that are formed from black holes.

• They are stars that form outside galaxies.

• They are stars that are ejected from their home galaxies due to significant events.

• They are stars that never belonged to any galaxy.

What happens when a companion star in a binary system goes supernova?

• The other star becomes a black hole.

• The other star remains unaffected.

• The other star is ejected at high speed, potentially becoming a rogue star.

• The other star is pulled into a black hole.

How can a star become a hypervelocity star?

• By forming outside a galaxy.

• By being ejected from a binary system near a black hole.

• By being part of a supernova explosion.

• By colliding with another star.

What is the most common way a star becomes rogue?

• By being ejected from a binary system.

• By forming in intergalactic space.

• By the collision of galaxies.

• By being consumed by a black hole.

Why is it difficult for rogue stars to form outside galaxies?

• Because rogue stars need a supernova to form.

• Because there is no dust and gas in intergalactic space.

• Because rogue stars require a black hole to form.

• Because rogue stars need a companion star to form.
