The radiation astrochemistry of sulphur
in the interstellar medium and the outer Solar System

by Duncan V. Mifsud (HUN-REN ATOMK)

When: 2024-03-07 Thursday 11:00 AM

Where: HUN-REN ATOMKI, lecture hall (Debrecen, Bem tér 18/c)

Additional information:

- This seminar introduces the [ | article
of the month ] 2024/1:

Sulphur ion implantation into O 2 , CO, and CO 2 ices: Implications for the
formation of sulphur-bearing molecules in the Kuiper Belt, [ | Icarus
411 (2024) 115926 ] .


The astrochemistry of sulphur presents many as yet unresolved challenges. In
dense interstellar clouds, for instance, observed sulphur is depleted by up
to three orders of magnitude compared to its expected cosmic abundance;
whereas reasonable chemical mechanisms for the formation of even simple
sulphuretted molecules on the surfaces of icy outer Solar System objects
continue to elude researchers. In this talk, I shall present an overview of
the current “state-of-the-science” with regards to sulphur astrochemistry
before going on to discuss our laboratory’s efforts at further comprehending
radiation-induced sulphur chemistry in astronomical environments. As part of
this talk, I will highlight the physico-chemical effects of implanting
sulphur ions in astrophysical ice analogues.
