WebSep 12, 2024 · As the temperature of a blackbody increases, the total emitted power also increases. Quantitatively, Stefan’s law expresses this relation as P ( T) = σ A T 4 where A is the surface area of a blackbody, T is its temperature (in kelvins), and σ is the Stefan–Boltzmann constant, σ = 5.670 × 10 − 8 W / ( m 2 ⋅ K 4). matthew stone facebookWebNov 17, 2024 · A = α M 2. ; T: A = α M 2. then it gaines mass by amount of d m and it increases the area by d A. So at. T + d t: A + d A = α ( M + d m) 2. And the gained mass at this d t time will be equal to d m = d A β or can we say d m = A β. Edit: Lets thing mass m around the surface of the black hole.
