Noun
a hypothetical object capable of absorbing all the electromagnetic radiation falling on it
Source: WordNeta black body maintained at a constant temperature is a full radiator at that temperature because the radiation reaching and leaving it must be in equilibrium Source: Internet
Alpher and Herman made it clear that what they had called "the temperature in the univerese" the previous year referred to a blackbody distributed background radiation quite different from sunliight". Source: Internet
At Harvard, Lewis also wrote a theoretical paper on the thermodynamics of blackbody radiation in which he postulated that light has a pressure. Source: Internet
In a nuclear photonic rocket, a nuclear reactor would generate such high temperatures that the blackbody radiation from the reactor would provide significant thrust. Source: Internet
Given, for example, the color magnitudes B and V which are calibrated to be equal for an A0V star (e.g. Vega ), the stellar color temperature is given by the temperature for which the color index of a blackbody radiator fits the stellar one. Source: Internet
The 15000 K blackbody spectrum (dashed line) matches the visible part of the stellar SPD much better than the blackbody of 9500 K. All spectra are normalized to intersect at 555 nanometers. Source: Internet
