H2 fluorescent emission from the diffuse interstellar medium
David A. Neufeld
A simple analytic model is presented to predict the near-IR H2 fluorescent line intensities emitted by diffuse interstellar clouds with a Plummer density profile. It is applicable…
JWST-IPA: Chemical Inventory and Spatial Mapping of Ices in the Protostar HOPS370 -- Evidence for an Opacity Hole and Thermal Processing of Ices
Himanshu Tyagi, Manoj P., Mayank Narang +35
The composition of protoplanetary disks, and hence the initial conditions of planet formation, may be strongly influenced by the infall and thermal processing of material during th…
The densities in diffuse and translucent molecular clouds: estimates from observations of C and from 3-dimensional extinction maps
David A. Neufeld, Daniel E. Welty, Alexei V. Ivlev +7
Newly-computed collisional rate coefficients for the excitation of C in collisions with H, presented recently by Najar and Kalugina (2020), are significantly larger than th…
Re-evaluation of the cosmic-ray ionization rate in diffuse clouds
M. Obolentseva, A. V. Ivlev, K. Silsbee +6
All current estimates of the cosmic-ray (CR) ionization rate rely on assessments of the gas density along the probed sight lines. Until now, these have been based on observations o…
Dissociative recombination of rotationally cold ArH
Ábel Kálosi, Manfred Grieser, Leonard W. Isberner +11
We have experimentally studied dissociative recombination (DR) of electronically and vibrationally relaxed ArH in its lowest rotational levels, using an electron--ion merged-be…
