Light is in a star produced by high energy levels raising the heat to a point that the molecules of the elements in the star start to "glow". Simply stated, the light spectrum of different materials causes specific anomalies in the measured light, and it is possible to detect the temperature of the star AND the elements by analyzing the light spectrum that it gives off.
spectral analysis
OR intsead of saying "GLOW"??
YOU CAN SAY BY ITS' BRIGHTNESS You can look at a star and light from a spectrometer. This is what tells what the element on the star is.
Scientists can study the composition of distant stars using a technique called spectroscopy. By analyzing the light emitted by stars, they can determine the elements present in the star's atmosphere. This information helps scientists understand the chemical makeup and evolution of stars.
Most astronomical telescopes are outfitted with spectrometers. These devices examine the color of light from a star in very fine detail. The lack of certain colors, known as Fraunhofer lines or absorption lines, in the spectrum indicate the presence of certain chemical elements.
The answer is long and complicated, and it is too long to place here.
You need to read an entire encyclopedia articles on spectroscopy and the chemical composition of intersteller objects.

They use a special kind of device that reads the wavelengths shown in the stars, i think. The wavelengths react differently to certain chemicals, but based on these wavelengths, the scientists can tell which chemicals are present or absent in stars.
Scientists are able to use an instrument known as a spectrograph to examine the sun's layers. By examining the lines in the sun's spectrum, they are able to determine the kind of gas causing this a layer or line. Every element has a unique set of lines that offer a unique solar fingerprint. Examining these fingerprints enable scientists to determine what the sun or any other star is made of.
Different chemical elements emit (or absorb) certain specific frequencies of light. When the light from a star is split in to it's rainbow spectrum of light, certain parts of the spectrum will be black (in absorption spectra) or brighter (in emission spectra). By comparing these lines to the known emission and absorption spectra of elements, the composition of a stars atmosphere can be determined.
Each element on the Periodic Table will emit a different color, it set if colors, when being burned. Astronomers look at the "Phase-Shift" of the color spectrum (or rainbow) that any given star emits. The Phase Shift refers to how the colors are balanced. More if one color over another will tell an astronomer what that star is made of.
They use the spectra to organize planets/stars by the color and temperature. =) That's all! :D

What characteristics are used to describe stars?
Stars can be described by their temperature, size (diameter), brightness (luminosity), color, composition, and age. These characteristics help scientists classify and study stars in the universe.
Why is that so many facts about stars are based on theory?
Many facts about stars are based on theories because stars are extremely distant and complex objects that are difficult to study directly. Scientists use theories to make predictions and explanations based on the data they can observe, such as light, temperature, and composition of stars. These theories are constantly refined and updated as more data becomes available through telescopes and other observational methods.
How do astronomers determine the composition of distant celestial objects?
Astronomers use spectroscopy to determine the composition of distant celestial objects. By analyzing the light emitted or absorbed by the object, they can identify the elements present based on their unique spectral fingerprints. This technique allows astronomers to study the chemical makeup of stars, galaxies, and other astronomical bodies.
How do scientist study the star?
Scientists study stars by observing their light, radiation, and other forms of energy using telescopes and other instruments. They analyze the spectra of light emitted by stars to understand their composition, temperature, and age. By observing stars over time, scientists can track changes and better understand their life cycles.
To calculate the mass of a star scientists study?
the orbits of binary stars
What do scientists study to learn about the properties of stars?
Scientists study stellar spectra to learn about their properties such as temperature, chemical composition and relative chemical abundances, radial velocity, rotational speed etc.

Scientists study rocks using what important criteria?
Scientists study rocks based on their mineral composition, texture, structure, and formation process. These criteria help scientists understand the history of the rock, its properties, and the environmental conditions that existed when the rock was formed.
How are stars analized?
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.
What is an astrochemist?
An astrochemist is an expert in astrochemistry, the study of the chemical composition of stars and outer space.
