Abstract

Calculations of the emission spectrum of a homogeneous plane layer of pure hydrogen plasma taking into account nonlinear effects (the influence of bremsstrahlung and recombination radiation of the layer itself on its Menzel factors) Morchenko et al., Ap&SS, Vol. 357, article id. 119 (2015) show that the blue component of the optical continuum during the impulsive phase of large flares on dMe stars originates from the near-photospheric layers Grinin and Sobolev, Afz, Vol. 13, 587 (1977). The gas behind the front of a stationary radiative shock wave propagating in the red dwarf chromosphere toward the photosphere is not capable of generating the blackbody radiation observed at the maximum brightness of the flares.
