In our Galaxy the total number of such flash stars is about $10^{11}$. The power and frequency of stellar flares are enough to populate all cosmic ray spectrum up to particle energy $10^{15}$\,eV. Electrogasodynamic model of charged particle acceleration in flares of dwarf stars is considered. The physical mechanism includes the acceleration of particles by electric field behind plasma shock wave originating by stellar flare.</abstract><trans-abstract xml:lang="ru">Во вспышках карликовых звёзд Главной последовательности происходит генерация заряженных частиц. В нашей Галактике полное число таких звездных вспышек составляет около $10^{11}$. Мощности и частоты звездных вспышек вполне достаточно для обеспечения спектра космических лучей до энергии частиц $10^{15}$\,eV. Рассматривается электрогазодинамическая модель ускорения заряженных частиц во вспышках карликовых звёзд. Физический механизм включает в себя ускорение частиц электрическим полем, создаваемым плазменной ударной волной, порождённой звездной вспышкой.</trans-abstract></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Yodh G.
