The hottest stars are white or blue, cooler stars are yellowish.
Cooler still are the orange stars. The coolest stars appear red.
That's how the spectrum of a star is related to its surface temperature.
The reason is that the hotter the star, the shorter the wavelength at which the light is most intense in its spectrum. Blue light is of shorter wavelength than red.
What else can I help you with?
What part of a star is it that astronomers study in order to learn its characteristics of a star?
Astronomers study the spectrum of light emitted by a star to learn about its characteristics. By analyzing the composition of elements, temperature, and density of a star, astronomers can determine its size, age, brightness, and life cycle stage.
Analysis of the of a star reveals the composition of the star?
That's done by analyzing the star's spectrum.
The mass of a star can be determined by studying?
binary star systems
What are 3 things that we can learn about a star by observing it's spectrum?
By observing far away stars in our galaxy through a spectroscope, we are able to see the spectrum that appears from the substances in these stars. Each element has a unique spectrum when light is shone through it, so we are able to determine what elements make up certain stars.
If the spectrum of a star is blue shifted which is the star moving?
If the spectrum of a star is blue-shifted, it indicates that the star is moving towards the observer. This shift occurs because the wavelengths of light from the star are compressed as it approaches, resulting in a shift towards the blue end of the spectrum. This phenomenon is a consequence of the Doppler effect, which applies to all types of waves, including light.

What is a star's emission spectrum?
The emission spectrum of a star is the spectrum of frequencies for emitted electromagnetic radiation during the transition of an atom's electrons from a high-energy state to a low-energy state. The emission spectrum can differ depending on the temperature and composition of the star.
Analysis of the of a star reveals the composition of the star?
That's done by analyzing the star's spectrum.
How do scientists determine the elements in a star since they cannot collect a sample from a star?
They analyze the star's spectrum. Each element produces characteristic lines in a spectrum.
How do scientists determine the element present in a star?
By the star's spectrum.
Does the spectrum of light from a star have no gaps?
The spectrum of light from a star appears continuous, without gaps, because it is a result of the superposition of light emitted at different wavelengths. This continuous spectrum is produced as the star emits light across a range of wavelengths leading to a smooth distribution of colors in the spectrum.
The mass of a star can be determined by studying?
binary star systems
What does the spectrum of a star determine?
The spectrum of a star provides information about its temperature, composition, and motion. By analyzing the spectrum, astronomers can determine the star's chemical makeup, age, and even whether it is moving toward or away from Earth.
What does a star emits?
The spectrum is a kind of analysis of the light emitted by a star.
What can a stars spectrum tell astronomers about a star?
What elements the star is made of.
What are 3 things that we can learn about a star by observing it's spectrum?

What part of the star is responsible for the dark lines in its spectrum?
The dark lines in a star's spectrum are caused by absorption of specific wavelengths of light by the elements in the star's outer atmosphere. This absorption occurs when the elements in the atmosphere absorb photons of specific energies, leading to the creation of dark absorption lines in the spectrum.
