The ir wavelength for metals on asteroid

WebJul 1, 2024 · 2.2. Corrections applied to asteroid spectra. Asteroids that have low albedos and are observed at high temperatures (while they are close to the Sun) often emit a significant amount of flux at near-infrared wavelengths starting around 2 μ m.Because this is emitted light, rather than reflected sunlight, asteroid spectra that displayed thermal … Webdependence of the wavelength of the thermal emission peak on distance from the Sun is illustrated in terms of these simple thermal models. In Fig. 2 model fluxes vs. heliocen-tric distance are plotted for a 100-km asteroid observed at the wavelength of the thermal emission peak and at 20 µm. In recent years much attention has been given to near-
