Spectroscopy and Chemical Synthesis of Interstellar Ice Analogues
ABSTRACT. Pure ices of amorphous methanol, CH3OH(X 1A0), were irradiated at 11 K by 5 keV electrons at 100 nA for 1 hr. These energetic electrons simulate ...
Sulfur-bearing hydrides in UV-illuminated gas and grains - HALThese experiments appear to indicate that any cir- cumstellar pyrimidine would be easily destroyed by UV photons or cosmic ray particles soon after delivery to ... Astrophysics of Dust in Cold CloudsTwig peel affects the surface of the bone and gives it the ridged appearance of an iced-lolly stick that has been broken in two pieces (Novak pers comm). Halford Hewitt Trivia 2006If we take T = 500 K and Td = 35 K, the sticking coefficient is estimated to be S ? 0.2 and the H2 formation efficiency, ?, is close to unity (Hollenbach & ...
