3 Ways to Slingshot a Star

The video explores the Gaia mission's findings of stars being ejected from the Milky Way. It discusses the role of the supermassive black hole Sagittarius A* in dynamical ejection, where stars are flung out due to gravitational interactions. Another mechanism, binary ejection, occurs when a star in a binary system is propelled into space following a supernova explosion. Additionally, stars can be ejected from dense star clusters through complex gravitational interactions. These processes contribute to the presence of rogue stars traveling through intergalactic space.

What are the main reasons that stars can be ejected from their galaxies?

Describe the process of dynamical ejection and how it affects stars in a binary system.

Explain the concept of binary ejection and its significance in the context of star formation.

What role does a supermassive black hole play in the dynamics of stars within a galaxy?
