The B 2 FH paper described key aspects of the nuclear physics and astrophysics involved in how stars produce these heavy elements. By scrutinizing the table of nuclides , the authors identified different stellar environments that could produce the observed isotopic abundance patterns and the nuclear processes that must be responsible for them.

This article is a list of notable unsolved problems in astronomy.Problems may be theoretical or experimental. Theoretical problems result from inability of current theories to explain observed phenomena or experimental results.
Evolution captures both the history of an organism via its phylogeny, and the history of natural selection working on function to produce adaptations. [6] There are several reasons why natural selection may fail to achieve optimal design (Mayr 2001:140–143; Buss et al. 1998).
In biology, phylogenetics (/ ˌ f aɪ l oʊ dʒ ə ˈ n ɛ t ɪ k s,-l ə-/) [1] [2] [3] is the study of the evolutionary history of life using genetics, which is known as phylogenetic inference. It establishes the relationship between organisms with the empirical data and observed heritable traits of DNA sequences, protein amino acid sequences ...
The subdisciplines of theoretical astrophysics are: Compact objects – this subdiscipline studies very dense matter in white dwarfs and neutron stars and their effects on environments including accretion. Physical cosmology – origin and evolution of the universe as a whole. The study of cosmology is theoretical astrophysics at its largest scale.
John R. Gribbin (born 19 March 1946) [1] is a British science writer, an astrophysicist, and a visiting fellow in astronomy at the University of Sussex. [2] His writings include quantum physics, human evolution, climate change, global warming, the origins of the universe, and biographies of famous scientists. He also writes science fiction.
