Stellar Remnants

We consider these stars 'dead' because they no longer are carrying out fusion in their cores.

• White Dwarfs

• Red Dwarfs

• Red Giants

• Brown Dwarfs

The upper limit of a white dwarf's mass is which of the following?

• 1 solar mass

• 1.5 solar masses

• 1.4 solar masses

• .5 solar masses

Which of the following is the fate that awaits our sun?

• Suffer core collapse and explode in a type II supernova and become a neutron star

• Collapse without exploding and become a black hole

• Eject its outer layers and leave behind its core as a white dwarf

• Explode as a type Ia supernova

Where does most of the iron in the universe come from?

• Iron is fused in the core of some white dwarf stars and released during a Type 1a supernova.

• Iron is created as light leaves a star and interacts with the star's atmosphere.

• Recycled metal on Earth is launched into space.

• Iron was created during the big bang.

What spectacular event follows the red super giant phase for a large or massive star when it starts fusing iron in its core?

• Big Bang

• Supernova

• Planetary Nebula

• Nova

Low to Medium mass stars like our Sun will not explode in a Supernova because they do not have enough mass. They will 'puff off' their outer layers of gas leaving a __________ nebula behind.

• planetary

• supernova remnant

• shockwave
