What are the four characteristics that scientists use to classify stars?
Stars are classified by four different characteristics. Apparent magnitude (brightness) and absolute magnitude (how bright it would appear at 10 parsecs from the earth). Luminosity, another measure of brightness, compares the star to the sun's brightness. Spectral classifications are measured by the star's temperatures. Finally stars are signed a number by scientists through the Morgan-Keenan System.
What is the H R diagram?
The H-R diagram is a graphical tool used to classify stars according to color, temperature, spectral type, luminosity, and evolutionary stage. H-R stands for Hertzsprung-Russell.

What spectral class is the sun?
Our Sun has a spectral class of G2V.
What does spectral disturbance mean?

What two star characteristics does Hertzsprung Russell diagram compare?
The HR Diagram compares the relationship between the stars' absolute magnitudes or luminosities versus their spectral types or classifications and effective temperatures.

What are the seven fundamental stellar spectral types?
The seven fundamental stellar spectral types are O, B, A, F, G, K and M. Also, what are their relationships to the stellar temperatures?
Stellar-classification?
Madalynne Braseltonstellar classification is the classification of stars based on their spectral characteristics
Who was the first person to classify stellar spectra by temperature?
Many people were involved in the current spectral classes.The person who first realised that the spectral sequence then categorised was in fact temperature, was Cecilia Payne.See related link for more information on her.
How do you determine a stars temperature?
By analysing it's spectral characteristics. See link for more information
What are some star characteristics that can be identified by spectral analysis?
it determines their composition and age and direction of shift
