On the present Earth, the primary condensible substance — water vapor — represents only a few percent of the mass of the atmosphere. While the effects of the latent heat of phase change are dynamically significant, the direct effects of mass loss...

Environment plays a major in role in the evolution of galaxies. This is particularly true of low mass dwarf galaxies where more massive galaxies dramatically affect the local gravitational potential. Isolated galaxies offer a unique test bed for...

Cosmic rays comprise only about one billionth of interstellar particles in the Milky Way, but have as much energy as the thermal gas. Low energy cosmic rays affect the chemistry and thermodynamics of interstellar through collisional processes...
