JWST Detection of Hydrocarbon Ices and Methane Gas on Makemake

The Astrophysical Journal Letters
JWST/NIRSpec observations of Makemake reveal a chemically complex surface and evidence of gaseous CH _4 . Our spectral modeling indicates a surface composition consisting of CH _4 , CH _3 D, and possibly CH _3 OH, combined with aggregates of C _2 H _2 ...

Infrared spectroscopy of interstellar apolar ice analogs

Astronomy & Astrophysics, 1997
Apolar ices have been observed in several regions in dense clouds and are likely dominated by molecules such as CO, CO(2) and the infrared inactive molecules O(2) and N(2). Interstellar solid CO has been well characterized by ground-based high resolution measurements.
