How come any analysis of stars shows they are made up of gaseous materials and no rock and metal?

First, I am not debating with you. I spent several pages and gave you every possible benefit of the doubt, but in the end you demonstrated you were doing nothing except wasting everybody's time. As such, every post you make will be deleted on principle, I will not allow anyone to circumvent bans. Any readers however are of course welcome to join the discussion, so long as you are not merely here to waste time, and will read and respond rather than just repeat.
However, this is a question some readers may be interested in because it exposes a major flaw with how the round earth model is defended. This claim that analysis of stars shows they are made of gaseous materials? It is simply not true. The scientific area here is spectroscopy, and chances are 99% of the people using it as an argument understand nothing about it. Those that do, however, will acknowledge that this is not how it works.
Spectroscopy is a way to examine the spectrum of light emitted by an object. There are three important concepts here. First is the emission spectra; these are specific patterns of wavelengths of light that correspond uniquely to each element. You can detect elements such as hydrogen and iron this way. Second is the absorption spectra. This is the most important to spectroscopy; according to the REer, the gas that composes the Sun absorbs certain wavelengths of light, and so these will be absent from the spectra emitted by the Sun. The Sun is not the only object to have an absorption spectra however, even empty space does. Light passes through pockets of gas, and is thus affected. The most important concept here is the continuous spectra, however. This is the full spectrum of light, without any lines absorbed. This is the initial state, and it is emitted by anything that radiates heat. The round earther will tell you that the spectra of the Sun tells you it is composed of gas, but that is simply wrong, spectroscopy can only tell you that those gases are between us and a source of light and heat. The physical object itself emits a continuous spectrum, this is observed here on Earth as well, the absorption spectra tells us only the composition of what surrounds the light source.
This is a perfect indication of the problem with round earthers. This argument was made with a fundamental lack of understanding, the assumption that because RET says it, anything contrary is wrong, but DET isn't wrong, it's different. The above argument is accurate only when the Sun is entirely composed of gas. Otherwise it only tells us about the vicinity: the spectra emitted by a hot, bright solid object will always be identical.
