Stellar Chromospheres: The Source of UV Emission

  • Jeffrey Linsky
Chapter
Part of the Lecture Notes in Physics book series (LNP, volume 955)

Abstract

The lower layer of a star’s atmosphere, its photosphere, has a thermal structure that decreases outward controlled by the balance of radiative and convection heat from below and the loss of radiation to space. With increasing height in a stellar atmosphere, magnetic heating processes become important in the energy balance, forcing the temperature to increase with height in a region called the chromosphere. Magnetic heating processes include the damping of different types of magnetic waves and the reconnection of magnetic fields.
