The strength and pattern of the absorption lines does vary among the stars. Some stars have strong (dark) hydrogen lines, other stars have no hydrogen lines but strong calcium and sodium lines. Are their abundances different? No. When scientists learned more about the physics of the atom, the...

Wherever he goes, people from all walks of life--homemakers, chiefs of industry, politicians, and film stars--seek his blessings and advice. Amazingly, he manages to make each one feel special and cherished. Who is this playfully profound, childlike, ever-smiling guru whose avowed mission ...
The nature and Equation of State (EOS) of such matter are still very poorly known while they have broad impacts on many interesting issues in both astrophysics and nuclear physics. In particular, the nuclear symmetry energy encoding the energy cost to make nuclear matter more neutron rich has ...

rest of the universe reaches Earth in the form of electromagnetic radiation. By interpreting that radiation,astronomerscan glimpse the earliest epochs of the universe, measure the general expansion of the universe, and determine the chemicalcompositionofstarsand theinterstellar medium. Just as the ...
