Interaction of HS with H atoms on grain surfaces under molecular cloud conditions
Julia C. Santos, Harold Linnartz, Ko-Ju Chuang
Hydrogen sulfide (HS) is thought to be efficiently formed on grain surfaces through the successive hydrogenation of S atoms. Its non-detection so far in astronomical observatio…
CRIRES high-resolution near-infrared spectroscopy of diffuse interstellar band profiles. Detection of 12 new DIBs in the YJ band and the introduction of a combined ISM sight line and stellar analysis approach
A. Ebenbichler, A. Postel, N. Przybilla +7
A high spectral resolution investigation of diffuse interstellar bands (DIBs) in the near-infrared ( band) is conducted to test new methods, to confirm and improve existing par…
The EDIBLES survey IV. Cosmic ray ionization rates in diffuse clouds from near-ultraviolet observations of interstellar OH
Xavier L. Bacalla, Harold Linnartz, Nick L. J. Cox +6
We report cosmic ray ionization rates towards ten reddened stars studied within the framework of the EDIBLES (ESO Diffuse Interstellar Bands Large Exploration Survey) program, usin…
Formation of interstellar methanol ice prior to the heavy CO freeze-out stage
D. Qasim, K. -J. Chuang, G. Fedoseev +3
The formation of methanol (CH3OH) on icy grain mantles during the star formation cycle is mainly associated with the CO freeze-out stage. Yet there are reasons to believe that CH3O…
Methanol ice co-desorption as a mechanism to explain cold methanol in the gas-phase
N. F. W. Ligterink, C. Walsh, R. G. Bhuin +3
Methanol is formed via surface reactions on icy dust grains. Methanol is also detected in the gas-phase at temperatures below its thermal desorption temperature and at levels highe…
Infrared spectra of complex organic molecules in astronomically relevant ice matrices. I. Acetaldehyde, ethanol, and dimethyl ether
J. Terwisscha van Scheltinga, N. F. W. Ligterink, A. C. A. Boogert +2
Context. The number of identified complex organic molecules (COMs) in inter- and circumstellar gas-phase environments is steadily increasing. Recent laboratory studies show that ma…
