Linear and weakly nonlinear stability analyses of Rayleigh–Bénard convection (RBC) in a radiating Newtonian fluid are studied in the paper. The optical properties of the Newtonian fluid are considered to be independent of the wavelength of radiation. A gray medium thus assumed allows us to consider two asymptotic cases: (a) …
