... as opposed to a primitive notion of wave theory proposed by contemporaries Hooke and Huygens but also on a careful experiment (1727) on stellar aberration by James Bradley (1692–1762). It could easily be explained by the particle theory of light, but not wave theory, until the concept of energy was fully...

.... – And 17 are shielded from staple isotopes formed by neutron absorption in boxes 6 and 14, respectively. They need quite another environment with a flux of free protons. Fig. 28.3 Graphical description of B²FH theory. Adapted from Clayton , D. D., Principles of Stellar Evolution...

...—the Saha equation—that gave the relationship between the observed spectrum of a star and the temperature of the region of the star emitting the light. Cecilia Payne used this equation in an ingenious way to totally change our understanding of the stellar abundances of the elements. In the beginning...

... Q, and its angular momentum J (in Chap. 5, it is called L). This was a very impressive result. It means that there are no physical differences between two BHs with identical values of M, Q, and J, though one might have been made from a collapsing stellar...

... the brightness. Happily, transition probabilities can be measured in a lab; they can also be calculated using the wave functions from the Schrödinger equation (Chap. 13). Thus, we obtain the abundance of the hydrogen from a combination of the observed brightness of the stellar spectral line and the transition...

... or stars contain elements discovered on Earth. The stellar spectra can reveal the composition of stars and their movement speed. From these stellar spectra, astrophysicists found that all stars are moving away from Earth. This indicates the expansion of our universe. With these powerful applications...
