What us the relation between temperature and brightness of stars?
The temperature of a star is directly related to its brightness. Hotter stars emit more energy and appear brighter, while cooler stars emit less energy and appear dimmer. This relationship is described by the Stefan-Boltzmann law, which states that the luminosity of a star is proportional to the fourth power of its temperature.
What is a graph that shows relationship between a stars magnitude and temperature?
The Hertzsprung-Russell (HR) diagram is a graph that shows the relationship between a star's magnitude (luminosity) and temperature. It plots stars based on their color (temperature) and brightness (magnitude), allowing astronomers to classify stars and understand their evolutionary stage.
Describe the relationship between the size of a star and its luminosity?
The luminosity of a star is closely related to its size, with larger stars generally being more luminous than smaller ones. This relationship is partly explained by the star's surface area and temperature; a larger star has a greater surface area to radiate energy and often has a higher temperature, both of which contribute to increased luminosity. According to the Stefan-Boltzmann law, a star's luminosity is proportional to the fourth power of its temperature and the square of its radius, highlighting the significant impact of size on a star's brightness.
Is the relationship of brightness to temprture for these stars puzzling or does it make sense?
The relationship between brightness and temperature for stars generally follows the Stefan-Boltzmann law, which states that a star's luminosity (brightness) is proportional to the fourth power of its temperature. This relationship makes sense as hotter stars emit more energy across all wavelengths, resulting in greater brightness. However, factors like distance, size, and composition can complicate this relationship in specific cases, leading to some apparent anomalies that might seem puzzling at first glance. Overall, while the basic principle is clear, real-world observations can introduce complexities.
The H-R diagram shows the relationship between a star and acirc and 128 and 153s surface temperature and its?
The Hertzsprung-Russell (H-R) diagram illustrates the relationship between a star's surface temperature (or color) and its luminosity (or absolute brightness). Stars are typically plotted on this diagram with temperature decreasing from left to right, and luminosity increasing from bottom to top. The position of a star on the H-R diagram indicates its stage in the stellar lifecycle, with main sequence stars, giants, and white dwarfs occupying different regions. Thus, a star's temperature and luminosity provide insights into its size, age, and evolutionary status.
IN main sequence stars what is the relationship between brightness and temperature?
Brightness tells you the temperature and mostly temperature would tell the brightness of the star that we are talking about.
Who discovered the relationship between the star temperature and brightness?
Hertzsprung and Russell.
Who discovered the relationship between a star brightness and temperature?

How is the brightness of a Cepheid star calculated by knowing the period?
The brightness of a Cepheid star is determined by its period-luminosity relationship, which is a relationship between the star's variability period and its intrinsic luminosity. By measuring the period of a Cepheid star, astronomers can use the period-luminosity relationship to calculate its luminosity, and from there determine its apparent brightness as observed from Earth.
Who Discovered The Relationship Between The Stars Temperatures?
The relationship between a star's temperature and brightness was discovered independently around 1910 by Ejnar Hertzsprung and Henry Norris Russell. The relationship between these to parameters is depicted in a Hertzsprung-Russell diagram or H-R diagram.
In main-sequence star how does brightness relate to temperature?
The brightness is very similar to the temperature, the brightness relies on the temperature

Who discovered the relationship betweens a star's temperature and its brightness?
Ejnar Hertzsprung and Henry Norris Russell,working independently, realized the relationship between a star's temperature and its brightness.Together, in 1910, they formed what is now known as the Hertzsprung--Russell diagram or HR Diagram.It's a scatter graph showing the relationship between a star's absolute magnitudes, their spectral types and temperatures.

What does the HR diagram depict?
The HR diagram, also known as the Hertzsprung-Russell diagram, depicts the relationship between the luminosity and temperature of stars. It shows how stars are distributed in terms of their brightness and temperature, allowing astronomers to classify stars based on these characteristics.
What does the hurtzsprung-russell diagram predict?
The Hertzsprung-Russell diagram predicts the relationship between a star's luminosity (brightness) and temperature, allowing astronomers to classify stars based on their properties. It shows the correlation between a star's temperature and its absolute magnitude, helping to understand their evolutionary stage and lifecycle.
