Comparisons of interstellar CH+ and H2
Description
We have obtained Copernicus observations of H2 toward stars in the Pleiades and 23 Orionis because of their importance in understanding the formation of interstellar CH+. No model of CH+ equilibrium seems to agree very well with these observations; in particular, we apparently can exclude the suggestions that CH+ is formed either from collisions between vibrationally excited H2 and C+ or from radiative association of C+ and H2. These data do suggest that there is a correlation between the amounts of rotationally excited H2 and CH+ which are present. Our observations of the Pleiades also help interpretations of the reflection nebulae near these stars
