Can someone explain why the type of spectrum depends on the temperature of the atmosp
The atmospheres of stars are not hot enough to produce an emission line spectrum Therefore, stars are found to emit an absorption line spectrum
I dont think the premise is correct there.
The corona is the outer atmosphere of the sun and it has a much higher temperature than the visible 'surface' or photosphere... Millions of Kelvin. But its also very low density so you normally need an eclipse in order to see it.
What you do see when you look at the corona during an eclipse is emission spectra.

Ok whatever it is something is preventing the sun/other stars from having an emission spectrum and making it have an absorption spectrum, why?
Have you done blackbody and continuum radiation?
the vast majority sunlight and starlight comes from hot plasma in the photosphere, in the hot plasma the electrons and protons are separate rather than being organised into hydrogen atoms, the plasma can and does emit light over a continuous range of frequencies - the plasma acts as a black body
emission spectra can only come from atoms i.e. electrons bound with a nucleus.
you do actually get emission spectra from atoms the suns atmosphere - but you don't normally see it. The chromosphere has a red colour that is caused by the hydrogen alpha emission line - but it's only noticeable during an eclipse or if you use a narrow band filter.
