What used to help humans determine the temperature of stars?
spectral analysis
What are the 4 variables astronomers use to classify stars?
Astronomers use temperature, luminosity, size, and color to classify stars. These factors help categorize stars into different spectral types and determine their position on the Hertzsprung-Russell diagram.
The light from stars are used to determine what?
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.
Why does the colour of the stars tell you about it?
The color of a star can provide information about its temperature and age. Hotter stars appear blue or white, while cooler stars appear orange or red. This color can help astronomers determine the star's stage in its life cycle and characteristics like size and brightness.
What are two things help determine what type of precipitation will fall from the sky?
1 of the things that help determine the precipitation is the temperature
Which factor does not help determine the height length AND period of the wave?
temperature
What will best help determine the direction of heat flow in a system?
temperature
How can one determine soil temperature effectively?
One can determine soil temperature effectively by using a soil thermometer to measure the temperature at different depths in the soil. This can help provide accurate readings and insights into the temperature variations within the soil.
Why do humans have hair under their arms?
Humans have hair under their arms to help regulate body temperature and to reduce friction between the skin.
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.
What are the four characteristics that scientists use to classify stars?
Stars are classified by four different characteristics. Apparent magnitude (brightness) and absolute magnitude (how bright it would appear at 10 parsecs from the earth). Luminosity, another measure of brightness, compares the star to the sun's brightness. Spectral classifications are measured by the star's temperatures. Finally stars are signed a number by scientists through the Morgan-Keenan System.
What does the color of a star help to determine about the star?
The color of a star determines the heat of the star. For example; a white dwarf star does not produce nearly as much heat as our sun does. However, one day, our sun will turn into a white dwarf star. When this happens there will not be enough heat to live on Earth.
