Neutral hydrogen in interplanetary space.
Abstract
Several problems relating to interplanetary hydrogen are discussed. Various possible interplanetary sources and sinks for H and He atoms are considered, and their contributions to the distribution of interplanetary neutral gas are compared. A theoretical description of the penetration of interstellar H and He into interplanetary space is presented with reference to observations of interplanetary neutral gas. The implications of interplanetary H for the solar wind are examined, and some qualitative aspects of the passage of the solar system through an interstellar H cloud are discussed. Future research goals are outlined.
