Definition and Meaning of Star Color and Temperature
The relationship between a star's color and its temperature is a fundamental concept in astrophysics. Stars emit light across a spectrum of colors, which is primarily determined by their surface temperature. The color of a star can range from red to blue, with each color corresponding to a specific temperature range. For instance, red stars are cooler, typically ranging from about two thousand to four thousand degrees Celsius, while blue stars are much hotter, often exceeding ten thousand degrees Celsius. This correlation is described by Wien's Law, which states that the wavelength of light emitted by a black body is inversely proportional to its temperature.
Understanding this relationship helps astronomers classify stars and understand their life cycles. The temperature affects not only the color but also the luminosity and size of the star. For example, a hotter star will not only appear blue but will also be significantly more luminous than a cooler star of the same size.
