These two types of stars clearly must have different properties because they form distinct groups on a Hertzsprung-Russell diagram. I have also read that red supergiants can form elements up to around carbon by nuclear fusion, whereas red supergiants can form up to iron, however there doesn't seem to be a clear cut answer as to what main sequence star mass produces a ed giant and which produces a red supergiant, or what exactly happens after the red giant and red supergiant phase. Some sources seem to use only one term when describing the star cycle, and other sources use both but not consistently... I am very much confused! I would appreciate if someone could clear up the differences between these two star types. Thank you :)
