Microgravity experiments on the collisional behavior of Saturnian ring particles
Daniel Heißelmann, Jürgen Blum, Helen J. Fraser +1
In this paper we present results of two novel experimental methods to investigate the collisional behavior of individual macroscopic icy bodies. The experiments reported here were…
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…
