A star's spectral classification is determined by its temperature because temperature affects the ionization and excitation of atoms in the star's atmosphere. Hotter stars emit more high-energy photons, which can ionize elements and produce distinct spectral lines. These lines, observed in the star's spectrum, reveal the presence of different elements and their ionization states, thereby allowing astronomers to classify the star into specific spectral types (like O, B, A, F, G, K, M). Consequently, the temperature directly influences the star's spectral characteristics, informing its classification.
Spectral class is a classification system for stars based on their temperature and spectral characteristics. It categorizes stars into different groups, such as O, B, A, F, G, K, and M, with O being the hottest and M being the coolest. Spectral class is indicated by a letter, with additional subtype information denoted by a number.
A K type star has a surface temperature ranging from about 3,500 to 5,000 degrees Celsius. It is cooler than stars with earlier spectral types (such as O, B, and A stars) but hotter than stars with later spectral types (such as M stars).
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.
Scientists measure the brightness, color, and spectral lines of stars to determine their temperature and composition. By analyzing the light emitted by stars, scientists can infer important information about their properties. The temperature of a star is usually determined by examining the peak wavelength of its emitted light, while the spectral lines reveal the elements present in the star's atmosphere.
The spectral type of a star measures its temperature and determines its color, luminosity, and size. It is determined by the characteristics of the star's spectrum, such as the absorption lines caused by elements in its atmosphere. Astronomers use spectral types to classify stars based on their physical properties.
No. K spectral type stars (which are orange) temperature is ranging from 5,000-3,500. A spectral type stars (which are blue-white) temperature is ranging from 7,500-11,000.
Two stars of the same spectral class must have the same temperature and color. This classification system groups stars based on their temperature, with each spectral class representing a specific range of temperatures.

Spectral class is indicated by a letter, with additional subtype information denoted by a number.
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.
The spectral class letters in astronomy represent the temperature and color of stars. The sequence starts with O (hottest and bluest stars) and ends with M (coolest and reddest stars). The spectral class letters are O, B, A, F, G, K, and M.
