SUMMARY:Ice and Surface Chemistry in Space - Prof Wendy Brown\, University
  of Sussex
DTSTART:20210504T100000Z

DESCRIPTION:Ultra-high vacuum surface science methodologies are ideally su
 ited to studying the interaction of molecules with model astrophysical gra
 in surfaces. Dust grains are found in a number of environments in space\, 
 including comets\, planetary atmospheres and in the interstellar medium (t
 he ISM\, the space between the stars). Dust grains comprise carbonaceous a
 nd silicaceous material and\, at the low temperatures in space (20-30 K)\,
  are usually covered in multi-component molecular ices. These ices are typ
 ically dominated by water and simple alcohols\, such as methanol\, but als
 o contain a broad spectrum of organic species such as esters\, aldehydes\,
  ketones\, carboxylic acids and nitriles\, to name but a few. This talk wi
 ll describe some of the work that has been done in our group to investigat
 e the adsorption\, reaction and processing of astrophysically relevant ice
 s. The physical chemistry data that we obtain can be used to give informat
 ion about grain-surface processes that are relevant to star and planet for
 mation.
