Desorption of hot molecules from photon irradiated interstellar ices
J. D. Thrower, D. J. Burke, M. P. Collings +10
We present experimental measurements of photodesorption from ices of astrophysical relevance. Layers of benzene and water ice were irradiated with a laser tuned to an electronic tr…
Infrared spectroscopy of solid CO-CO2 mixtures and layers
F. A. van Broekhuizen, I. M. N. Groot, H. J. Fraser +2
The spectra of pure, mixed and layered CO and CO2 ices have been studied systematically under laboratory conditions using infrared spectroscopy. This work provides improved resolut…
A 3-5m VLT spectroscopic survey of embedded young low mass stars II; OCN
F. A. van Broekhuizen, K. M. Pontoppidan, H. J. Fraser +1
The 4.62m (2164.5 cm) `XCN' band has been detected in the -band spectra of 34 deeply embedded young stellar objects (YSO's), observed with high signal-to-noise and hig…
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…
Results from a VLT-ISAAC survey of ices and gas around young stellar objects
K. M. Pontoppidan, H. Fraser, F. L. Schoeier +3
General results from a 3-5 micron spectroscopic survey of nearby low-mass young stellar objects are presented. L and M-band spectra have been obtained of \~50 low mass embedded you…
