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 is the primary cause of stars being ejected from the center of the Milky Way?

• Gravitational interactions with a supermassive black hole

• Magnetic fields

• Supernova explosions

• Collisions with other galaxies

In a binary star system, what happens to the remaining star when its companion is captured by a black hole?

• It becomes a black hole

• It gains energy and is ejected from the galaxy

• It loses energy and slows down

• It forms a new binary system

What event leads to the ejection of a star in a binary system with a massive companion?

• The massive companion colliding with another star

• The massive companion losing its magnetic field

• The massive companion exploding into a supernova

• The massive companion becoming a black hole

How can stars be ejected from dense star clusters?

• By losing mass rapidly

• Due to magnetic field disruptions

• By colliding with other galaxies

• Through gravitational interactions with neighboring stars

What was unique about the star discovered in 2014 that was ejected from a star cluster?

• It was eight times the size of the sun

• It was traveling slower than other stars

• It was the first star to be ejected from a cluster

• It was the smallest star ever found
