A cryogenic ice setup to simulate carbon atom reactions in interstellar ices

D. Qasim, M. J. A. Witlox, G. Fedoseev +7

The design, implementation, and performance of a customized carbon atom beam source for the purpose of investigating solid-state reaction routes in interstellar ices in molecular c…

HCN/HNC intensity ratio: a new chemical thermometer for the molecular ISM

A. Hacar, A. D. Bosman, E. F. van Dishoeck

Context. The gas kinetic temperature (TK) determines the physical and chemical evolution of the Interestellar Medium (ISM). However, obtaining reliable TK estimates usually require…

Lack of PAH emission toward low-mass embedded young stellar objects

V. C. Geers, E. F. van Dishoeck, K. M. Pontoppidan +4

PAHs have been detected toward molecular clouds and some young stars with disks, but have not yet been associated with embedded young stars. We present a sensitive mid-IR spectrosc…

Photodesorption of water ice: a molecular dynamics study

S. Andersson, E. F. van Dishoeck

Absorption of ultraviolet radiation by water ice coating interstellar grains can lead to dissociation and desorption of the ice molecules. These processes are thought to be importa…

Searching for molecular hydrogen mid-infrared emission in the circumstellar environments of Herbig Be stars

C. Martin-Zaidi, E. F. van Dishoeck, J. -C. Augereau +2

Context: Molecular hydrogen (H2) is the most abundant molecule in the circumstellar (CS) environments of young stars, and is a key element in giant planet formation. The measuremen…

The c2d Spitzer spectroscopic survey of ices around low-mass young stellar objects II: CO2

Klaus M. Pontoppidan, A. C. A. Boogert, Helen J. Fraser +6

This paper presents Spitzer-IRS spectroscopy of the CO2 15.2 micron bending mode toward a sample of 50 embedded low-mass stars in nearby star-forming clouds, taken mostly from the…
