If a star belongs to class G, what is its surface temperature range?

The classification of stars into spectral classes is based on their surface temperatures, and class G stars are characterized by a specific temperature range indicative of their physical properties. Stars classified as G typically have surface temperatures between 5,000 and 6,000 Kelvin.

Within this range, G-class stars can include some well-known examples such as our Sun, which falls comfortably within this temperature range. The presence of certain spectral lines, particularly those associated with ionized metals, provides further confirmation of this classification system.

The temperature range is significant because it plays a crucial role in determining the star's color, luminosity, and overall properties. G-class stars are often yellow in color, reflecting the temperature they emit most effectively.

Understanding the characteristics of G-class stars helps in broader stellar classification and contributes to our knowledge of stellar evolution and various astronomical phenomena.
