Analysis of the neutral hydrogen within I KPC of the Sun

Abstract

Neutral hydrogen about the LSR is assumed to approximate a plane-parallel layer. Line profiles -10 > I > 250 ) are analyzed using differential motion equations and small nonuniform circular effects are found. Eight latitude positions, symmetric with respect to the plane, yield small velocities (< 3 km/ sec) which are found to be functions of z-position relative to the plane. The result is a "shearing" effect whereby the gas above and below the plane has a slightly different velocity from the gas closer to the plane.
