... Далее при достижении определенной температуры в центре звезды загорается гелий, а водород продолжает гореть в слоевом источнике и т.д. Уравнения использованные в этой программе достаточно очевидны: во первых это уравнение генерации энергии в ядерном синтезе около центра звезды, во вторых перенос энергии к поверхности излучением и конвекцией, уравнение гидростатического равновесия (в котором газовое давление и давление излучением уравновешиваются гравитацией) и уравнение сохранения массы. ...

... GCR and SCR are primary cosmic rays. 10-15 years after the discovery of cosmic radiation (1919) there emerged two main avenues of investigation in the physics of cosmic rays (CR): 1) nuclear - elucidation of the origin of elementary particles and nuclear interactions; and 2) astrophysical (space physics) - solution of the problem related to the origin and variations (changes in intensity) of CR. ... Besides, the CR flux in interplanetary space is, strictly speaking, not isotropic. ...
