CH+ can form near stars in the Pleiades via the endothermic reaction of C+ with H 2 in
photoelectrically heated gas flowing through the cluster. This conclusion follows from either
of two models, one in which gas and dust remain well mixed, the other in which radiation
pressure separates dust from gas in a layer well outside the H 2 dissociation front near each
star. Other common features of the two models include the following.(1) The observed
insensitivity of N (CH+) to spectral type constrains the effective wavelength for photoelectron�…
