Linking ice and gas in the Serpens low-mass star-forming region
G. Perotti, W. R. M. Rocha, J. K. Jørgensen +3
The interaction between dust, ice, and gas during the formation of stars produces complex organic molecules. While observations indicate that several species are formed on ice-cove…
Collisions of small ice particles under microgravity conditions (II): Does the chemical composition of the ice change the collisional properties?
C. R. Hill, D. Heißelmann, J. Blum +1
Context: Understanding the collisional properties of ice is important for understanding both the early stages of planet formation and the evolution of planetary ring systems. Simpl…
Collisions of small ice particles under microgravity conditions
C. R. Hill, D. Heißelmann, J. Blum +1
Planetisimals are thought to be formed from the solid material of a protoplanetary disk by a process of dust aggregation. It is not known how growth proceeds to kilometre sizes, bu…
AKARI observations of ice absorption bands towards edge-on YSOs
Y. Aikawa, D. Kamuro, I. Sakon +9
To investigate the composition and evolution of circumstellar ice around low-mass YSOs, we observed ice absorption bands in the near infrared (NIR) towards eight YSOs ranging from…
Thermal desorption characteristics of CO, O2 and CO2 on non-porous water, crystalline water and silicate surfaces at sub-monolayer and multilayer coverages
J. A. Noble, E. Congiu, F. Dulieu +1
The desorption characteristics of molecules on interstellar dust grains are important for modelling the behaviour of molecules in icy mantles and, critically, in describing the sol…
A Zero-Gravity Instrument to Study Low Velocity Collisions of Fragile Particles at Low Temperatures
D. M. Salter, D. Heißelmann, G. Chaparro +14
We discuss the design, operation, and performance of a vacuum setup constructed for use in zero (or reduced) gravity conditions to initiate collisions of fragile millimeter-sized p…
