RFTS 2025 - The Evolution of More Massive Stars

Why do massive stars evolve more rapidly than lower-mass stars?

• They have more nuclear fuel.

• They have stronger gravitational forces.

• They are closer to the center of the galaxy.

• They have higher core temperatures.

Where are elements heavier than carbon primarily formed?

• In the atmospheres of stars

• In the centers of massive stars

• In the outer layers of planets

• In the cores of low-mass stars

What is the endpoint of fusion in massive stars?

• Oxygen

• Iron

• Carbon

• Silicon

What happens when massive stars exhaust their nuclear fuel?

• They explode as supernovae.

• They form new planets.

• They become black holes.

• They turn into white dwarfs.

What is the primary difference in chemical composition between globular and open clusters?

• Globular clusters have fewer heavy elements.

• Globular clusters have more hydrogen.

• Open clusters have more helium.

• Open clusters have fewer heavy elements.

What is the primary composition of the first generation of stars?

• Hydrogen and helium

• Carbon and oxygen

• Silicon and iron

• Gold and silver

What is the significance of Eta Carinae in the study of massive stars?

• It is the closest star to Earth.

• It is a supergiant with significant mass loss.

• It is a star with no heavy elements.

• It is the smallest known star.

What is the primary process that builds up elements in stars?

• Nucleosynthesis

• Oxidation
