What is similarities between apparent brightness and absolute brightness?
Both relate to brightness; both are measured in the same units; both are used for astronomical objects such as stars or galaxies.
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.
Why are pulsating variable stars useful for finding distances to globular clusters?
It really depends on the type of star, but for certain star types, there is a relationship between the period and the absolute brightness, so if the period is observed, the absolute brightness can be deduced. Yes. It seems like this question is about the Cepheid variables.
Who are the astronomer divided the stars into six magnitudes of brightness?
The astronomer who divided stars into six magnitudes of brightness was Hipparchus, a Greek astronomer active in the 2nd century BCE. He developed a system to categorize stars based on their apparent brightness, with the first magnitude representing the brightest stars and the sixth magnitude representing the faintest stars visible to the naked eye. This magnitude scale laid the groundwork for modern astronomical classification of stellar brightness.
What system classifies stars according to its brightness?
The system that classifies stars according to their brightness is called the magnitude scale. This scale measures the apparent brightness of stars as seen from Earth, with lower numbers indicating brighter stars; for example, a star with a magnitude of 1 is brighter than one with a magnitude of 5. Additionally, the absolute magnitude scale measures the intrinsic brightness of stars at a standard distance of 10 parsecs. Together, these systems help astronomers categorize and compare stars based on their luminosity.
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 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 brightness color of star?
The brightness and color of a star are related to its temperature and size. Hotter stars appear blue or white and are brighter, while cooler stars appear red or orange and are dimmer. The brightness of a star can also vary based on its distance from Earth.
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.
What persons discovered the relationship between a stars temperature and its brightness?
edwin hubble
Do stars have the same brightness and sizes?
No. Stars vary greatly in size and brightness.
What is similarities between apparent brightness and absolute brightness?
Both relate to brightness; both are measured in the same units; both are used for astronomical objects such as stars or galaxies.
How size and brightness of stars are related?
They are related because the bigger the star the brighter u can see it otherwise the smaller the star the duller it is to see.
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.
Which two groups of stars can have similar brightness?
Variable stars and main sequence stars can have similar brightness. Variable stars, like Cepheid variables, can fluctuate in brightness over time, while main sequence stars maintain a relatively stable brightness due to their fusion processes.
Do stars vary greatly in size and color only.?
No. Stars vary in lots of aspects, including:* Diameter * Mass * Color (and the related surface temperature) * Chemical composition * Density (related to mass and diameter) * Brightness
What color of the star is the brightest?
The hottest stars are blue or blue-white. Brightness is a different matter, and is not strictly related to color.
