Classification of Stars
Question 1 of 3
This question is about the Hertzsprung-Russell diagram (HR diagram) and the classification of stars.
Stars can be classified by their colour.
Describe the relationship between the temperature and the colour of a star.
The diagram below shows the axes for a HR diagram.
Complete the diagram by adding the main sequence, red giant and white dwarf regions.
State what is meant by the term absolute magnitude.
This question is about the classification of stars and the HR diagram.
Explain why the Moon does not appear on the HR diagram.
A student has drawn a HR diagram below.
Mark the following on the students diagram.
- A main sequence star much larger than the sun. Label this star A.
- A star with the lower temperature than the Sun but much greater brightness. Label this star B.
- A star with the same temperature as the sun but lower brightness when compared at the same distance from Earth. Label this star C.
- A white dwarf star. Label this star D.
This question is about the life cycle of stars and the HR diagram.
What type of stars are found in the region labelled A on the HR diagram above?
What type of stars are found in the region labelled B on the HR diagram above?
What type of stars are found in the region labelled C on the HR diagram above?
Stars with a absolute magnitude of 0 are dimmer than start with an absolute magnitude of +5. True or False?
Describe the stars in the region labelled C.
