The differences in spectrum are mainly due to:
* Differences in temperature between the stars
* Differences in chemical composition
* Differences in relative movement (redshift / blueshift, due to the Doppler effect)
The chemical composition of the star.
Stars can range from blue to red depending on temperature and mass, with yellow stars in the middle and white stars on the back end of the spectrum.
Because the spectrum consist of another element
because all of the different lines of a star's elements appear together i its spectrum, making the pattern different everytime
scientists can tell the stars composition and temperature from its spectrum. Hope tht helps :]
Most stars exhibit a continuous spectrum, which contains all wavelengths of light in a continuous distribution. This is often referred to as a blackbody spectrum due to its smooth curve.
A spectrograph is a device that separates light from stars and other objects into its different wavelengths to produce a spectrum. This allows astronomers to study the composition, temperature, and other properties of the object emitting the light through analysis of the spectrum.
Its elemental composition.

Stars appear white in the night sky because they emit light across a broad spectrum of colors, with a balance of different wavelengths that our eyes perceive as white.
Orange stars have a K-type spectrum with a wide distribtion of brightness.
Different wavelengths on the spectrum are seen as different colors within the visible light section of the spectrum.
