How can we identify the chemical elements present in stars?
A) The peak of the star’s thermal emission tells us its temperature: Hotter stars peak at shorter (bluer) wavelengths. B) The total amount of light in the spectrum tells us the star’s radius. C) We can identify chemical elements present in the star by recognizing patterns of spectral lines that correspond to particular chemicals.
How many light years away is the closest star to our Sun?
