Answer:
The Core?
Explanation:
You would think that heat would come from the core but I'm not sure
Because it creates energy and food for different beings
Spectral analysis proposes that there is no hydrogen fusion roughly
speaking. They are hot since they are very thick. So if you are a convinced
high density and temperature and still not doing synthesis, you must be small.
Also, stellar evolution models are founded on the observation of planetary
nebulae, where stars have shed most of their mass after being red giants. The
physics designates a small, hot, central remainder.
