Abstract
Like planets in the solar system, exoplanets form, evolve, and interact with their host stars in many ways. Exoplanets form out of protostellar disks, which contain positive ions (H+, H\(^+_2\), and H\(_3^+\)) and other radicals produced when molecules in the disk are photo-dissociated by stellar UV and X-ray photons and then charge-exchanged by protons in the stellar wind. These positive ions become the formation seeds of complex molecules including simple organics.

In this book I express all wavelengths in nanometers rather than angstroms to follow the physics convention. 1 nm = 10 Å.
