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 else can I help you with?
Temperature and brightness of stars are indicated by what?
Temperature of stars is indicated by their color, with blue stars being hotter than red stars. Brightness of stars is indicated by their luminosity, which is how much light a star emits.
The temperature and brightness of stars are indicated by their what?
The temperature of stars is indicated by their color, with cooler stars appearing more red and hotter stars appearing bluer. The brightness of stars is measured in terms of luminosity, which is the total amount of energy emitted per unit of time.
The hertzsprung-russell diagram graphs stars' brightness and?
The Hertzsprung-Russell diagram graphs stars' luminosity or brightness against their surface temperature or color. This diagram is a powerful tool used in astronomy to classify and understand the life cycle and evolutionary stage of stars. It helps astronomers study the relationship between a star's temperature, luminosity, size, and stage of evolution.
What indicates a stars temperature and brightness?
A star's temperature is indicated by its color, with hotter stars appearing blue and cooler stars appearing red. Brightness is measured using the star's apparent magnitude, with higher magnitudes representing dimmer stars and lower magnitudes representing brighter stars.
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.
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.
What persons discovered the relationship between a stars temperature and its brightness?
edwin hubble
In main-sequence stars how does brightness relate to temperature?
The brightness is very similar to the temperature, the brightness relies on the temperature
What indicates stars of brightness and temperature?
The color of stars determines temperature. Red/brown stars are cooler, blue stars are hotter, and yellow stars are in between. Brightness also has some correlation with color. Both are based on many varying factors however.
Temperature and brightness of stars are indicated by what?
Temperature of stars is indicated by their color, with blue stars being hotter than red stars. Brightness of stars is indicated by their luminosity, which is how much light a star emits.
What is the temperature and brightness of stars indicated by?
color
The temperature and brightness of stars are indicated by?
its color :)
What are the temperature and brightness of stars are indicated?
Their Color!(:
What determines how bright stars are?
Size and temperature determine the brightness of stars.
Are stars different sizes and brightness?
Yes! Some stars are supergiants, which means that they are high-mass stars. They explode in a supernova towards the end of their life. These stars are generally brighter than others. A star's brightness also depends on its temperature. Red stars are the coolest temperature, followed by orange, yellow, white and blue stars.
What is an astrometer?
An astrometer is a device designed to measure the brightness, relation, or apparent magnitude of stars.
How can you clasiffy the stars?
by temperature, size, brightness, distance and color
