Basic Properties of Stars
100
The end stage of a lower mass star.
What is a white dwarf?
100
This layer is the hottest layer of the sun.
What is the corona?
100
This is the type of binary system we can see with the naked eye or with a telescope.
What are visual binaries?
100
In this zone, the energy made in the core travels the fastest to the surface.
What is the convection zone.
100
The order of the Harvard Classification System.
O, B, A, F, G, K, M
200
High mass stars end in either of these stages.
What are neutron stars and black holes?
200
The only binary system we can see with the naked eye is located here.
Where is in the big dipper constellation?
200

This is the type of binary system we can detect with the wobbling of the larger star.

What is an astrometric binary.

200
This is the layer that we see when we look at the sun.
What is the photosphere?
200
Spectra produced by a thin gas in front of a hotter source.
What are Absorption Line Spectra?
300

The stage before the star reaches 10,000C and ignites. 

What is a protostar?

300
In the HR Diagram, a star in the upper right corner would be this type of star.
What is a red giant?
300
T/F:   Both stars in a binary system are always in the same life stage.
False
300
This textured area is caused by energy currents flowing up through the convection zone.
What are granules?
300
Stars start out in this category on the HR Diagram.
What are main sequence stars?
400

The cloud of gas that stars form in. 

What are nebulae?

400
Our suns complete spectral classification.
Type G2V.
400
This type of binary system can share material.
What is a contact binary?
400
This area of the sun is darker around the edges and lighter in the middle.
What is the limb?
400
All main sequence stars burn this element in their cores.
What is hydrogen?
500
The most massive of all stars end in this stage.
What is a black hole?
500
This area extends to over 90 AU from the sun.
What is the heliosphere/heliopause?
500

Matter within this area of a star is gravitationally bound to that star.

What is the roche lobe?

500
These areas are areas with parts that include the penumbra.
What are sun spots?
500
During this event, all of the heavier elements are created.
What is a super nova?
