Stellar Spectra

[astronut]

Would the spectrum of a star at say x degrees Kelvin have the same shape as a black body at the same temperature?

The only differences I presume would be that the stellar spectra would show absorption and emmission lines otherwise, superimposed on one another they would appear the same.

Am I correct?

A spectrum coming off a black body would be vastly different than one coming from a star. Because black bodies absorb electromagnetic radiation (as well as emit it), their spectrum will be inherently different than an object that simply emits EMR. :Chessy_Smile:

I will stay out of this one.

I understand what you are saying Radar. Maybe I need to be a bit clearer.

If you plot the curve of a black body at x degrees and then the curve of a star at x degrees, then would the curves not be the same with the exception of the emmission and absorption lines present in the stellar curve?

[Radar]

I think they would be different. :hmm:
