What are the 5 main groups of stars?

Question

We are doing the solar system and we have to do a stargazing word search but we have to answer the questions above it to find the words. The problem is tho is that i can't find the answer for the "5 main group of stars

Answer 1

There is more than one way to group stars.  For example, they may be grouped by where they appear on a plot of luminosity vs. spectral class, called the Hertzsprung-Russel (H-R) diagram.  They may be grouped by spectral type (of which there are 7), or some other way.  The H-R diagram has 4 groups:

 

 

1.  Supergiants

2.  Giants

3.  Main sequence

4.  White dwarfs

 

Perhaps you could add black holes as a 5th group of stars.  Can you tell us more about the context of the question?
