The B 2 FH paper [1] was a landmark scientific paper on the origin of the chemical elements. The paper's title is Synthesis of the Elements in Stars , but it became known as B 2 FH from the initials of its authors: Margaret Burbidge , Geoffrey Burbidge , William A. Fowler , and Fred Hoyle .
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 ...
A black dwarf is a theoretical stellar remnant, specifically a white dwarf that has cooled sufficiently to no longer emit significant heat or light. Because the time required for a white dwarf to reach this state is calculated to be longer than the current age of the universe (13.8 billion years), no black dwarfs are expected to exist in the ...
In his 1952 book The Creation of the Universe, Gamow explained Hans Bethe's association with the theory thus: [2] The αβγ paper with the figure referred to in the text. The results of these calculations were first announced in a letter to The Physical Review, April 1, 1948. This was signed Alpher, Bethe, and Gamow, and is often referred to ...

The non-stellar objects in the atlas are identified by type and designation. The chart scale is 100 arcsec/mm, matching that at the focus of an 8-inch f/10 Schmidt-Cassegrain. Star magnitudes are essentially Johnson V. Distance labels are given for stars within 200 light-years of the Sun. Proper motion arrows are given for stars with motions ...
The spectral type is not a numerical quantity, but the sequence of spectral types is a monotonic series that reflects the stellar surface temperature. Modern observational versions of the chart replace spectral type by a color index (in diagrams made in the middle of the 20th Century, most often the B-V color) of the stars.
