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…
Photodesorption of CO ice
Karin I. Oberg, Guido W. Fuchs, Zainab Awad +4
At the high densities and low temperatures found in star forming regions, all molecules other than H2 should stick on dust grains on timescales shorter than the cloud lifetimes. Ye…
Desorption of CO and O2 interstellar ice analogs
K. Acharyya, G. W. Fuchs, H. J. Fraser +2
Solid O2 has been proposed as a possible reservoir for oxygen in dense clouds through freeze-out processes. The aim of this work is to characterize quantitatively the physical proc…
Desorption rates and sticking coefficients for CO and N2 interstellar ices
S. E. Bisschop, H. J. Fraser, K. I. Oberg +2
We present Temperature Programmed Desorption (TPD) experiments of CO and N2 ices in pure, layered and mixed morphologies at various ice "thicknesses" and abundance ratios as well a…
A 3-5 micron VLT spectroscopic survey of embedded young low mass stars I: Structure of the CO ice
K. M. Pontoppidan, H. J. Fraser, E. Dartois +6
Medium resolution (lambda/Delta lambda = 5000-10000) VLT-ISAAC M-band spectra are presented of 39 young stellar objects in nearby low-mass star forming clouds showing the 4.67 micr…
