An interferometric study of the low-mass protostar IRAS 16293-2422: small scale organic chemistry
S. E. Bisschop, J. K. Jorgensen, T. L. Bourke +2
Aims: To investigate the chemical relations between complex organics based on their spatial distributions and excitation conditions in the low-mass young stellar objects IRAS 16293…
Infrared spectroscopy of HCOOH in interstellar ice analogues
S. E. Bisschop, G. W. Fuchs, A. C. A. Boogert +2
Context: HCOOH is one of the more common species in interstellar ices with abundances of 1-5% with respect to solid H2O. Aims: This study aims at characterizing the HCOOH spectral…
Testing grain-surface chemistry in massive hot-core regions
S. E. Bisschop, J. K. Jorgensen, E. F. van Dishoeck +1
A partial submillimeter line-survey was performed toward 7 high-mass young stellar objects (YSOs) aimed at detecting H2CO, CH3OH, CH2CO, CH3CHO, C2H5OH, HCOOH, HNCO and NH2CHO. In…
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…
Probing the Surfaces of Interstellar Dust Grains: The Adsorption of CO at Bare Grain Surfaces
Helen J. Fraser, Suzanne E. Bisschop, Klaus M. Pontoppidan +2
A solid-state feature was detected at around 2175 cm-1 towards 30 embedded young stellar objects in spectra obtained using the ESO VLT-ISAAC. We present results from laboratory stu…
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…
