| Popis: | 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. Comment: 3 pages, no figures; published in the Proceedings of the conference in honour of the 100th birthday of Academician V. V. Sobolev (St. Petersburg, September 21--25, 2015), pp. 219--221 (2017). This a slightly revised version |
