The Impact of Recent Advances in Laboratory Astrophysics on our Understanding of the Cosmos
D. W. Savin, N. S. Brickhouse, J. J. Cowan +11
An emerging theme in modern astrophysics is the connection between astronomical observations and the underlying physical phenomena that drive our cosmos. Both the mechanisms respon…
Carbon-Chain Species in Warm-up Models
George E. Hassel, Nanase Harada, Eric Herbst
In previous warm-up chemical models of the low-mass star-forming region L1527, we investigated the evolution of carbon-chain unsaturated hydrocarbon species when the envelope tempe…
Propagation of Low-Energy Cosmic Rays in Molecular Clouds: Calculations in Two Dimensions
Paul Rimmer, Eric Herbst
We calculate cosmic ray transport with a collisional Boltzmann Transport Equation, including E-M forces. We apply the Crank-Nicholson Method to solve this equation. At each time st…
Observing a column-dependent zeta in dense interstellar sources: the case of the Horsehead Nebula
P. B. Rimmer, E. Herbst, O. Morata +1
Context: Observations of small carbon-bearing molecules such as CCH, C4H, c-C3H2, and HCO in the Horsehead Nebula have shown these species to have higher abundances towards the edg…
New extended deuterium fractionation model: assessment at dense ISM conditions and sensitivity analysis
T. Albertsson, D. A. Semenov, A. I. Vasyunin +2
Observations of deuterated species are useful in probing the temperature, ionization level, evolutionary stage, chemistry, and thermal history of astrophysical environments. The an…
