The event that cannot be determined from the spectrum of a star is that the chemicals in the atmosphere of the star

Answer:

The chemicals in the core of the star

Explanation:

The spectrum of a star is of its atmosphere. The absorption or emission spectrum that is obtained indicates the chemical composition of the star's atmosphere. The peak wavelength obtained indicates the surface temperature of the star (using Wien's-Displacement Law). The shift in the spectrum indicates the motion of the star. If there is blueshift, it indicates that it is moving towards us where as if there is a red shift, it indicates that it is moving away from us.
