Chapter 1. 157 Where are the stars?

I'm a star that has lost my outer layers. All that's left is a white-hot core of carbon and oxygen atoms floating in a sea of degenerate electrons. Where should I be placed on the HR diagram?

I'm a star in the prime of my life. I'm in the process of converting my hydrogen core into helium. The inward pressure of gravity is balanced by the outward push from the radiation in my core. Where should I be placed on the HR diagram?

I'm a super star! I only fuse hydrogen into helium, just like the Sun, but I'm burning through that hydrogen far faster than one could ever imagine. I won't live long, and when I finish fusing my materials, I'm going out with a "Bang!" Where should I be placed on the HR diagram?

I'm a star, but just barely. I have enough mass for fusion to occur in my core, but I don't shine very brightly. On the positive side, I will outlive all of the other stars on the HR diagram. Where should I be placed on the HR diagram?

I've fused just about all of the hydrogen in my core, and now I'm fusing helium into carbon. I'm superhot in my core, but my outer layers are starting to drift away, and they're cooling. Where should I be placed on the HR diagram?
