Why does the sky after sunset mimic the blackbody spectrum?
Webenergy (integral of the curve) is proportional to the forth power of the absolute temperature (T4): hotter bodies radiate a lot more. The following plot shows the spectrum for temperatures from 273 K (0 °C) to 453 K (180 °C) in 20 °C steps. Back body radiation spectrum at 273, 293, 313, 333, 373, 393, 413, 433 and 453 K WebJun 5, 2024 · A newly discovered Jupiter-like world is so hot, it's being vaporized by its own star. With a dayside temperature of more than 7,800 degrees Fahrenheit (4,600 Kelvin), KELT-9b is a planet that is hotter than most stars. But its blue A-type star, called KELT-9, is even hotter -- in fact, it is probably unraveling the planet through evaporation. WebA blackbody that is twice as hot as the sun (about 12000 K) would have the peak of its spectrum occur at about 250 nanometers, which is in the UV part of the spectrum. ... found residence card
