What word means the same as luminosity?
Caution
Which correctly describes the relationship between the luminosity of two stars that are the same temperature?
If two stars have the same temperature, their luminosity is primarily determined by their size. According to the Stefan-Boltzmann law, luminosity increases with the fourth power of temperature and is also proportional to the surface area of the star. Therefore, if both stars have the same temperature but differ in size, the larger star will have a greater luminosity. If they are identical in size and temperature, they will have the same luminosity.
What describes the relationship between the luminosity of two stars that have the same radius?
The star that is hotter will have a higher luminosity.

Why would two stars have different sizes and tempertes but same luminosity?
The luminosity depends on what stage of its life cycle the star is in. Also, the apparent luminosity depends on the distance from earth.
Does apparent magnitude refer to real luminosity?
No. Apparent magnitude (or luminosity) means how bright a star (or other object) looks to us; absolute magnitude (or luminosity) refers to how bright it really is.
How do the stars luminosity compare with their radius?
A star's luminosity is related to its radius and temperature through the Stefan-Boltzmann law, which states that luminosity (L) is proportional to the square of the radius (R) multiplied by the fourth power of its surface temperature (T): (L \propto R^2 T^4). This means that for two stars of the same temperature, a larger radius results in significantly greater luminosity. Conversely, for stars of similar size, a higher temperature will lead to increased luminosity. Thus, both radius and temperature are crucial in determining a star's luminosity.
If the distance between us and a star is doubled with everything else remaining the same the luminosity?
The luminosity of the star would decrease by a factor of four. Luminosity is directly proportional to the inverse square of the distance from the star. So, if the distance is doubled, the luminosity decreases by a factor of 2^2 = 4.
What is the luminosity of gamma ceti?
It is a triple star system. Therefore every single star has different luminosity. However, as a whole the system is seen from earth at an appereant magnitude of 3.47, which means only %6 luminosity of the star vega.
How does the luminosity of a blackbody vary with its surface temperature?
Both the absorption and the luminosity of a blackbody in equilibrium increase in magnitude with increasing temperature, and the spectral distribution of the luminosity increases in frequency (decreases in wavelength).
How does luminosity affect the CHZ?
Luminosity affects the habitable zone (CHZ) by determining the distance at which a planet would need to be from a star to have the right temperature for liquid water to exist on its surface. Stars with higher luminosity would have habitable zones farther out, while stars with lower luminosity would have habitable zones closer in. This means that the size and location of the CHZ around a star depend on its luminosity.
What is a sentence with luminosity in it?
I was enthralled by the luminosity of the deep water jellyfish.
