This book provides readers with a clear progress to theoretical and observational astrophysics. It is not surprising that astrophysics is continually growing because very sophisticated telescopes are being developed and they bring the universe closer and make it accessible. Astrophysics Book presents a unique opportunity for readers to demonstrate processes do occur in Nature.
Abstract: “Brown dwarfs” is the collective name for objects more massive than giant
planets such as Jupiter but less massive than M dwarf stars. This review gives a brief
description of the classification and chemistry of low mass dwarfs. The current spectral
classification of stars includes L and T dwarfs that encompass the coolest known stars
and substellar objects. The relatively low atmospheric temperatures and high total
pressures in substellar dwarfs lead to molecular gas and condensate chemistry.
They were an extraordinary group of talents: Wigner won a Nobel Prize in theoretical physics; Szilard was the first to see that a chain reaction based on neutrons was possible, initiated the Manhattan Project, but left physics to try to restrict nuclear arms; von Neumann could solve difficult problems in his head and developed the modern computer for more complex problems; von Kármán became the first director of NASA's Jet Propulsion Laboratory, providing the scientific basis for the U.S.
