Hertzsprung -Russell Diagram
The color of the stars with the lowest temperature.
What is red?
The type of stars that are found in the upper left of the main sequence.
What are blue giants (supergiants)?
The type of star the sun will be at the end of its life when all fusion has stopped but remain on the H-R diagram.
What is a white dwarf?
The stage of a Sun-sized star that occurs when a white dwarf is so cool that it no longer puts out light.
What is a black dwarf?
The sun is a main sequence star. The group of stars on the H-R diagram that include yellow stars.
What is the main sequence?
The most abundant element in main sequence stars.
What is hydrogen?
The location of the Sun on a Hertzsprung-Russell diagram.
What is the main sequence?
The type of star that is very bright but cool.
What is a red giant?
An explosion-like event that occurs just before the formation of a neutron star from a massive star.
What is a supernova?
The type of star on the main sequence that is going to become a black hole.
What is a blue supergiant?
What is blue?
The type of star that will produce the heaviest elements as it goes through its life cycle.
What is a blue giant?
The types of stars found on the lower left of the Hertzsprung-Russell diagram.
What are white dwarfs?
The type of star that is very hot but dim.
What is a white dwarf?
The final form of a very massive star that consists of a very small, very dense mass.
What is a black hole?
The group of stars on the H-R diagram that will include neutron stars.
What are white dwarfs?
Red supergiants are found on the upper right of the H-R diagram. Betelgeuse is found on the upper right of the H-R diagram. The group of stars that include Betelgeuse.
What are red supergiants?
The type of star that will remain on the main sequence the longest.
What is a red dwarf?
The types of stars found on the upper right of the Hertzsprung-Russell diagram.
What are red giants?
The type of star that is both very bright and hot.
What is a blue giant?
The beginning of a star which often consists of matter left over after the death of another star.
What is a stellar nebula?
The percentage of visible stars that are on the main sequence.
What is 90%?
Blue supergiants are the most massive stars. The most massive stars become black holes. The final stage of a blue supergiant.
What is a black hole?
The element that makes up a white dwarf that started as a sun sized star.
What is carbon?
The two groups of stars on a Hertzsprung-Russell diagram that are not part of the main sequence.
What are red giants and white dwarfs?
Stars that are both cool and dim.
What are red dwarfs?
The type of main sequence star that will move to its next stage the soonest.
What is a blue supergiant?
The two forces that keep a star stable and on the main sequence.
What are gravity and fusion?
Closer stars look brighter. The Sun is the brightest star from Earth's perspective. It is the closest star to Earth.
What is the Sun?
What is size/brightness, and temperature/color?
