How are stars classified by size and temperature?
Stars are classified by size using the Hertzsprung-Russell diagram, which categorizes them based on luminosity and temperature. Stars are sorted into main sequence, giant, supergiant, or dwarf categories. Temperature determines a star's color, with hotter stars appearing blue-white and cooler stars appearing red.
Is the color of a star related to its size why or why not?
Yes, the color of a star is related to its size, primarily due to its temperature. Larger stars tend to be hotter and emit more energy, resulting in a blue or white appearance. In contrast, smaller stars are cooler and appear red or orange. This relationship is described by the Hertzsprung-Russell diagram, which illustrates how a star's color correlates with its temperature and size.
Do stars with the same color have the same size?
No, stars with the same color do not necessarily have the same size. Color in stars is primarily determined by their temperature, with hotter stars appearing blue and cooler stars appearing red. However, stars of the same temperature can vary significantly in size, as they may belong to different classes, such as dwarfs, giants, or supergiants. Thus, while color can indicate temperature, it does not provide a definitive measure of a star's size.
What is the relationship between a stars temperature and luminosity?
The relationship between a star's temperature and luminosity is described by the Stefan-Boltzmann Law, which states that a star's luminosity (total energy output) is proportional to the fourth power of its surface temperature (in Kelvin) multiplied by its surface area. This means that as a star's temperature increases, its luminosity increases significantly, assuming other factors like size remain constant. Additionally, hotter stars tend to be larger and more luminous than cooler stars, which further emphasizes the interconnectedness of temperature and luminosity in stellar properties.
What is the relationship between the color and the temperature of star?
The relationship is that the color is an indication of the star's surface temperature. For example, red stars are cooler, while blue stars are hotter. You can find more details in the Wikipedia article "Stellar classification".
What is the relationship between size and temperature?
Temperature influences glacier size.
What determines how bright stars are?
Size and temperature determine the brightness of stars.

What do stars have that depends on their size?
luminosity and temperature depend on their size but also on their mass
How can you clasiffy the stars?
by temperature, size, brightness, distance and color
What accounts of the differences in the appearance if the stars?
Their size, distance and temperature.
