Hi there,

So there is a dotpoint in the astro syllabus, which talks about analysing spectra of stars to give insights into their density.

So far, I have this:

The density of a star can be inferred from the width of the star’s spectral lines. A less dense star will have fewer collisions between atoms, and thus have very sharp and narrow spectral lines. On the other hand, a more dense star will have more collisions between atoms, resulting in blurred and broaden spectral lines.

Is there anything I missed or anything there which I could elaborate more on??

Thanks! :D
