Qué (quién) es effective temperature - definición

ESTIMATED TEMPERATURE OF AN ASTRONOMICAL BODY
Effective Temperature; Stellar temperature; Surface temperature (star); Solar temperature
  • The effective temperature of the [[Sun]] (5777 [[kelvin]]s) is the temperature a black body of the same size must have to yield the same total emissive power.

effective temperature         
¦ noun Physics the temperature of an object calculated from the radiation it emits, assuming black-body behaviour.
Effective temperature         
The effective temperature of a body such as a star or planet is the temperature of a black body that would emit the same total amount of electromagnetic radiation. Effective temperature is often used as an estimate of a body's surface temperature when the body's emissivity curve (as a function of wavelength) is not known.
Effective input noise temperature         
Equivalent noise temperature
In telecommunications, effective input noise temperature is the source noise temperature in a two-port network or amplifier that will result in the same output noise power, when connected to a noise-free network or amplifier, as that of the actual network or amplifier connected to a noise-free source. If F is the noise figure numeric and 290K the standard noise temperature, then the effective noise temperature is given by T n = 290(F' − 1).

Effective temperature

The effective temperature of a body such as a star or planet is the temperature of a black body that would emit the same total amount of electromagnetic radiation. Effective temperature is often used as an estimate of a body's surface temperature when the body's emissivity curve (as a function of wavelength) is not known.

When the star's or planet's net emissivity in the relevant wavelength band is less than unity (less than that of a black body), the actual temperature of the body will be higher than the effective temperature. The net emissivity may be low due to surface or atmospheric properties, including greenhouse effect.
