... 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. ...

... Using the uvby -photometry and proper motion data for about 5500 F stars within 80 pc from the Sun, we have studied velocity ellipsoid parameters and obtained the following results. 1) The sizw of all wllipsoid semiaxes increase systematically for groups of stars with the decrease of both temperature (at constant metallicity) and metallicity (at constant temperature). ... As a result, each of the three parameters - temperature, metallicity and velocity dispersion - is an age indicator. ...

... In addition, IZMIRAN comprises the St.Petersburg branch and magnetic ionospheric observatory in Kaliningrad. The history of IZMIRAN is largely that of investigating magnetic storms and sub-storms on the Earth surface, in circum-terrestrial and interplanetary space, initially by means of a network of ground stations of the Soviet Union (1930s - 1940s) and the nonmagnetic skunner "Zarja", then through the extensive use of magnetic measurements on artificial Earth satellites and automatic stations. ...
