... 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. ...

... The first column shows the kinematical diagrams, where is the angle between the line of sight on the object and the vector of rotation about Z -axis, and V S is objects line-of-sight velocity relative to an observer at rest at the position of the Sun. The straight lines are regression fits, whose slopes yield the subsystem?s rotation rate. The second column shows the relations between metallicity and distance from the Galactic plane. ... privious figure | next figure . ...

In other words, by far most meteorites falling on Earth are chondrites. Finds are meteorites that were not seen to fall but were subsequently discovered on the ground, often long after they landed. ... The vast majority of meteorites in museum and private collections around the world are finds, not falls. ...
