The light from stars can tell us what type of star it is (our Sun is a G type), the stars spectrum can tell us what elements are in the star, and its intristic brightness can help us determine how far away it is. Also, if there is a wobble in the star, or a change it the stars brightness can tell us if it has a planet.
Different chemicals emit and absorb light at various wavelengths. Astronomers can look at the wavelength of light coming from stars and determine which chemicals must be present.
Scientists measure the brightness, color, and spectral lines of stars to determine their temperature and composition. By analyzing the light emitted by stars, scientists can infer important information about their properties. The temperature of a star is usually determined by examining the peak wavelength of its emitted light, while the spectral lines reveal the elements present in the star's atmosphere.
Stars are analyzed through telescopic observations, spectroscopy, and measurements of their characteristics such as luminosity, temperature, mass, and composition. Scientists also study the light emitted by stars to determine their age and evolutionary stage. Additionally, stellar models and simulations are used to understand the complex processes happening within stars.
No. Stars emit light.
A spectrometer is used to determine the composition of stars, and how fast they are going relative to Earth.
Light wavelength and light spectrum i believe.
The masses of the two stars.

It is one tool that you can use. It is more for examining light and its properties, than for simple observation of stars, which you would use a telescope or binoculars for. It can be used to specifically examine the light to try and find out more about the stars and what they consist of.
Stars are the sources of light. If they did not emit light, there would be no stars and thus no astronomy.
parallax
Parallax is a method used to find the distances of stars.
Scientists measure the brightness, color, and spectral lines of stars to determine their temperature and composition.

spectral analysis
spectral analysis
The standard measure used to determine the brightness of a light bulb is called lumens.
