The surface temperature of a star is indicated by what physical characteristic?

The surface temperature of a star is indicated by its color or spectral type. Blue stars have higher surface temperatures compared to red stars. By analyzing the star's color and spectrum, astronomers can determine its surface temperature.


Which physical property of a star does the spectral type measure?

The spectral type of a star measures its surface temperature. This information is derived from the star's spectrum, which shows the distribution of light emitted at different wavelengths. Stars are classified into different spectral types, such as O, B, A, F, G, K, and M, based on their surface temperature and the dominant absorption lines in their spectra.


Of the spectral classes the highest temperature class is designated as what?

The O spectral class is the highest temperature class. Stars in this class are extremely hot and blue in color, with surface temperatures exceeding 30,000 K.


What are the names of the star colors?

The colors of stars are classified into categories such as red, orange, yellow, white, and blue, based on their surface temperature. The categorization is part of the spectral classification system used by astronomers to describe the characteristics of stars.


What is the surface temperature of Hercules the constallation?

Hercules is a constellation, not a star, so it doesn't have a surface temperature. However, the stars within the Hercules constellation have a range of surface temperatures depending on their specific spectral type.

What is the surface temperature of beta librae?

Beta Librae, also known as Zubenelgenubi, has an effective surface temperature of approximately 4,700 Kelvin. This temperature categorizes it as a K-type giant star, which gives it a characteristic orange hue. Its cooler temperature compared to the Sun contributes to its distinct color and spectral classification.

How much do astronomers use spectral analysis to classify stars?

Astronomers use the patterns of lines observed in stellar spectra to sort stars into a spectral class. Because a star’s temperature determines which absorption lines are present in its spectrum, these spectral classes are a measure of its surface temperature. There are seven standard spectral classes.

Can astronomers tell from the elements of a star what uts surface temperature is?

Yes, astronomers can estimate the surface temperature of a star based on its spectral type, which is determined by the elements present in its atmosphere. Each spectral type corresponds to a range of surface temperatures, allowing astronomers to make an educated guess about a star's surface temperature.

What is the star markabs surface tempiture?

The surface temperature of the star Markab is estimated to be around 12,600 Kelvin. This high temperature is indicative of its spectral type, which is B9IV. Markab is a main-sequence star located in the constellation Pegasus.


What is the temperature of an orange star?

An orange star typically has a surface temperature ranging from about 3,500 to 5,200 degrees Celsius. This temperature range corresponds to a spectral classification of K-type stars.


What is the surface temperature of Dubhe the star?

Dubhe, also known as Alpha Ursae Majoris, has a surface temperature of approximately 4,850 Kelvin. This temperature classifies it as a spectral type K0 III giant star. Its relatively cooler temperature compared to hotter stars contributes to its distinct yellow-orange hue.


What is the surface temperature for nu phoenicis?

Nu Phoenicis, also known as HD 100653, is a star located in the constellation Phoenix. Its surface temperature is approximately 5,800 Kelvin. This temperature is typical for a star of its spectral type, which is classified as F-type. This classification indicates that Nu Phoenicis is somewhat hotter than our Sun, which has a surface temperature of about 5,500 Kelvin.
