How many solar masses is sirius
WebSirius is a main sequence star of spectral type A0 or A1 and has a mass about 2.1 times that of the Sun. It has a companion star that has already evolved off the main sequence into a white dwarf, and hence was once the more massive of the two. WebThe Sun’s Flux (at the surface) is simply the amount of energy emitted from each piece of the solar surface per time. Thus, we expect units of ergs per squared-centimeter per second. Solar Flux at Surface = Solar Luminosity / Solar Surface Area = (3.8 x 1033 ergs/second) / (4 π r sun 2) = (3.8 x 1033 ergs/second) / (4 π (7 x 1010 cm)2 )
