Procyon luminosity

WebObjects in the universe send out an enormous range of electromagnetic radiation. Scientists call this range the electromagnetic spectrum, which they have divided into a number of categories. The spectrum is shown in Figure 5.6, with some information about the waves in each part or band. Figure 5.6 Radiation and Earth’s Atmosphere. WebIts total luminosity amounts to about 180 times solar.Arcturus has a J band magnitude of -2.2. In near-infrared wavelengths, it is fainter only than the red supergiant Betelgeuse (-2.9) in the constellation Orion and the red giant Mira variable star R Doradus (-2.6) in Dorado .
