Life & Death of Stars Review Game

Interstellar Reddening

• A. Group of widely scattered stars moving together in space. Not gravitationally bound into clusters.
• B. A star whose mass is too low to ignite nuclear fusion and that is heated by contraction.
• C. Balance between the weight of the material pressing downward on a layer in a star and the pressure in that layer. that layer.
• D. Process in which dust scatters blue light out of starlight and makes the star look redder.
• E. Group of stars that formed together and orbit a common center of mass.

Globular Cluster

• A. A group of stars that orbit the Milky Way's central black hole in a flat, disk-like structure.
• B. A dense, spherical collection of old stars bound together by gravity, typically found in the halo of galaxies.
• C. A young, open cluster of stars located within the spiral arms of a galaxy.
• D. A nebula composed of gas and dust, where new stars are actively forming.
• E. A black hole surrounded by an accretion disk emitting intense X-rays.

Open Cluster

• A. A tightly bound, spherical collection of old stars located in the halo of a galaxy.
• B. A loosely bound group of young stars formed from the same molecular cloud, often found in the disk of a galaxy.
• C. A massive collection of galaxies held together by gravity, forming a supercluster.
• D. A dense, compact group of stars orbiting close to a supermassive black hole.
• E. A star system where two or more stars are gravitationally bound and orbit each other.

Helium cannot fuse at the same temperature as hydrogen because it has twice the charge.

• True
• False

Stars in a binary system can evolve independently only if they are close together.

• True
• False

When debris loses momentum and settles, violent explosions (novae) occur.

• True
• False

Massive stars are unique because the fuse heavy elements.

• True
• False

Neutron stars can be as big as they want; they aren’t made of the same thing as black holes.

• True
• False

The Milky Way supports star formation because of the shape of its bands.

• False
