In stellar astronomy, the Algol paradox is a paradoxical situation when elements of a binary star seem to evolve in discord with the established theories of stellar evolution. [1] A fundamental feature of these theories is that the rate of evolution of stars depends on their mass: The greater the mass, the faster this evolution, and the more ...
Vestiges of the Natural History of Creation is an 1844 work of speculative natural history and philosophy by Robert Chambers.Published anonymously in England, it brought together various ideas of stellar evolution with the progressive transmutation of species in an accessible narrative which tied together numerous scientific theories of the age.
Stellar evolution is the process by which a star changes over the course of its lifetime and how it can lead to the creation of a new star. Depending on the mass of the star, its lifetime can range from a few million years for the most massive to trillions of years for the least massive, which is considerably longer than the current age of the ...
The book The Five Ages of the Universe discusses the history, present state, and probable future of the universe, according to cosmologists' current understanding. The book divides the timeline of the universe into five eras: the Primordial Era, the Stelliferous Era, the Degenerate Era, the Black Hole Era and the Dark Era.
The horizontal branch (HB) is a stage of stellar evolution that immediately follows the red-giant branch in stars whose masses are similar to the Sun's. Horizontal-branch stars are powered by helium fusion in the core (via the triple-alpha process) and by hydrogen fusion (via the CNO cycle) in a shell surrounding the core.
Subrahmanyan Chandrasekhar (/ ˌ tʃ ə n d r ə ˈ ʃ eɪ k ər /; [3] 19 October 1910 – 21 August 1995) [4] was an Indian-American theoretical physicist who made significant contributions to the scientific knowledge about the structure of stars, stellar evolution and black holes.
According to Axe, the research he provides with his book disproves Darwin's theory of evolution, revealing "a gaping hole has been at its center from the beginning." Click through 10 books that ...
His book Evolution of the protoplanetary cloud and formation of the Earth and the planets, [31] which was translated to English in 1972, had a long-lasting effect on how scientists thought about the formation of the planets. [32] In this book, almost all major problems of the planetary formation process were formulated, and some of them were ...
