Studying Fraunhofer lines helps to identify what on the stars?
Studying Fraunhofer lines helps identify the chemical composition of stars. These lines represent specific wavelengths of light that are absorbed by elements in a star's atmosphere. By analyzing the pattern of these lines, astronomers can determine which elements are present in the star.
What information does the color of a star provide?
The color of a star provides information about its temperature. Blue stars are hotter than yellow stars, which are hotter than red stars. This color-temperature relationship helps astronomers understand the life cycle and characteristics of stars.
What does an H-R diagram compare?
An H-R diagram compares the luminosity (brightness) of stars with their surface temperature. It helps classify stars based on their temperature and luminosity, allowing astronomers to study their characteristics and evolution.
What are two ways that stars can be classified according to the chart?
Stars can be classified based on their temperature, which is often indicated by their color, ranging from blue (hot) to red (cool). Additionally, they can be categorized by their luminosity or brightness, which is influenced by both their size and temperature. This classification helps astronomers understand the life cycle and characteristics of different types of stars.
What reveals the stars temperature?
The color of a star reveals its temperature. Blue stars are hotter than red stars, with temperatures ranging from about 10,000 K to 40,000 K and higher for the most massive stars.

What is the axes of Hertzsprung-Russell diagram?
The Hertzsprung-Russell diagram is a graphical representation of stars that plots their luminosity (or absolute magnitude) on the vertical axis against their surface temperature (or spectral class) on the horizontal axis. The temperature axis typically decreases from left to right, with hotter stars on the left and cooler stars on the right. This diagram helps classify stars into different categories, such as main sequence stars, giants, and white dwarfs, based on their luminosity and temperature.

What is the color of stars with the lowest surface temperature?
the color of stars with the lowest surface temperature is red
What does the temperature of stars tell us about luminosity?
The temperature of stars is closely related to their luminosity through the Stefan-Boltzmann Law, which states that a star's luminosity (L) is proportional to the fourth power of its temperature (T), expressed as (L \propto T^4). This means that even small increases in temperature can lead to significant increases in luminosity. Additionally, the temperature helps classify stars into different spectral types, which also correlates with their intrinsic brightness. Therefore, by measuring a star's temperature, we can infer its luminosity and understand its stage in the stellar lifecycle.
Blue vs red stars?
Red stars have the coolest surface temperature while blue stars have the highest surface temperature. NERD!
Which are more common low or high temperature stars?
Low-temperature stars, such as red dwarfs, are more common in the universe than high-temperature stars. They constitute the majority of stars in our galaxy, primarily due to their long lifespans and the fact that they form more frequently. High-temperature stars, like O and B types, are relatively rare and have shorter lifespans, which contributes to their lower abundance. Overall, the prevalence of low-temperature stars significantly outweighs that of high-temperature stars.
