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 ) WebThe orbital motion reveals that Sirius A, the brighter star, has 2.02 ± 0.03 solar masses and Sirius B, the white dwarf, has 1.00 ± 0.02 solar masses.
