Continuum and Line Emission of Flares on Red Dwarf Stars: Origin of the   Blue Continuum Radiation
  There are two types of models that explain the appearance of the quasi-blackbody radiation during the impulsive phase of stellar flares. Grinin and Sobolev [Astrophysics, Vol. 13, 348 (1977)] argue that the blue component of the optical continuum is formed in "the transition layer between the chromosphere and the photosphere." Katsova et al. [Astrophysics, Vol. 17, 156 (1981)] have "raised" the source of the white-light continuum up to a dense region in the perturbed chromosphere. In the present contribution (the main paper is published in "Astrophysics" [Vol. 59, 475 (2016); arXiv:1710.08008], we show that this statement in the work of Katsova et al. is erroneous.
