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.
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.
How do astronomers determine the surface temperatures of the stars?
Astronomers determine the surface temperatures of stars by analyzing their spectrum of light. Each star emits a unique spectrum based on its temperature which can be measured using instruments like spectrographs. By comparing the observed spectrum to known temperature profiles, astronomers can estimate the surface temperature of a star.
What units are distances to stars measured in and why?
Usually such distances are measured either in light-years, or in parsecs.
What is the surface temperature of Pegasus constellation?
The temperature of a constellation cannot be measured, as constellations are not physical objects themselves. Constellations are simply groupings of stars as seen from Earth. Each star within a constellation may have its own individual surface temperature, which can vary widely.

The distances to nearby stars can be measured by using . a. absolute magnitude c. color b. temperature d. parallax?
preallax
Are the stars measured in light years?
Stars are not measured in light years. The distance between them is.
How do you detect a temperature of a star?
The surface temperature can be estimated quite precisely from the color of the light. The temperature of the core can't be measured as directly, and must be estimated based on our knowledge of how stars work.
What is temperature measured by?
it is measured by a thermometer
How astronomers measure stellar temperatures?
Stellar temperature can be measured by analysing the spectrum of light that stars emit; shorter wavelengths correspond to higher temperatures.
Can air temperature be measured beyond the troposphere?
Air temperature can be measured beyond the troposphere.
Can air temperature not be measured beyond the troposphere?
Air temperature can be measured beyond the troposphere.

What is sequence stars?
Information on millions of stars shows that there is a relationship between temperature and brightness. Surface temperature is measured in degrees C and brightness is measured in absolute magnitude (the star's brightness at a standard distance). If all the stars are plotted on a graph of temperature against absolute magnitude, called a Hertzsprung-Russell diagram, very many of them lie close to a straight line that is called the Main Sequence. There are some stars that do not lie on the Main Sequence, notably the red giants that are very bright despite having a relatively low temperature. The Sun is right in the middle of the Main Sequence showing it is an average star in the middle of its life and very stable.
Is temperature measured in centimetres?
NO ... Barometric Pressure is measured in Centimeters or Inches (of Mercury.) Temperature is measured in Degrees Fahrenheit or Degrees Centigrade.
