Ice Origins of OCS and Chemistry of CS2-bearing Ice Mantles
Understanding the formation of carbonyl sulfide (OCS) in interstellar ices is key to constrain the sulfur chemistry in the interstellar medium (ISM), since it is the only ice S-bearing molecule […]

Assessing Realistic Binding Energies of Some Essential Interstellar Radicals with Amorphous Solid Water: A Fully Quantum Chemical Approach
In the absence of laboratory data, state-of-the-art quantum chemical approaches can provide estimates on the binding energy (BE) of interstellar species with grains. Without BE values, contemporary astrochemical models are […]

Peptides On Interstellar Ice
Peptides are organic compounds that play a crucial role in many biological processes, for example, as enzymes. A research team led by Dr Serge Krasnokutski from the Astrophysics Laboratory at […]
