A sound spectrogram measures the frequency and wavelengths of sound waves. The frequency is measured in Hertz and the wavelengths are measured in meters.
A photograph, map, or diagram of a spectrum.
The chemist who discovered that each element has a unique spectrogram.
Simply put, they don't differ except on what light they are spectrograms of. Any light can be analysed into a spectrogram. This includes sunlight. Spectrograms of lightbulbs and the light will differ from sunlight spectrograms in having fewer discrete frequencies (or wavelengths). This is because bulbs are much more simple than the sun, and involve just a few simple excitation reactions, whereas the Sun involves excitation processes, fusion processes and fission processes.
Planets can cause the star to have a very slight wobble or shift in normal path. This is picked up by a spectrogram. Some planetary systems actually have dust clouds around the star.

By studying the light from the stars. This is accomplished by examining closely the 'emission spectrum' that is obtained by passing the Light gathered by the telescope through a Prism which then in turn provides the Spectrogram. Absorbtion Spectrums identify the types of substances that make up the interstellar clouds that the Light passes through!

You use the fourier series to convert a signal from the time domain into the frequency domain, and vice versa. This is done by computing the sine waves that would be required to create the original signal. When done, you get a spectrogram, showing the intensity of each frequency (frequency domain) rather than the signal level over time (time domain).
