Irradiation of methanol ice on a sulfur-rich dust analogue at 25 K: a mid-infrared spectroscopic study

Key Points

The research aims to explore how methanol ice interacts with cosmic radiation on sulfur-rich dust analogues.
Irradiation of methanol-rich ices with cosmic rays and stellar winds
Use of mid-infrared spectroscopy to analyze the molecular products
Temperature maintained at 25 K during experiments
Novel sulfur-bearing molecular products were synthesized in the ice phase.
Irradiation effects produced detectable changes in the spectral characteristics of the ice.

Abstract

The irradiation of CH 3 OH-rich ices on top of sulfur-rich astrophysical dust grain analogues by galactic cosmic rays and stellar winds leads to the synthesis of novel sulfur-bearing molecular products in the ice phase. Image partially created using Google Gemini.
