2:00                Data, Data Everywhere! But which of it to use? The Need for Data Validation and Accountability in Laboratory Astrochemistry

Martin McCoustra

 

3:00                Discussion – lead by Martin McCoustra

to address: how do we agree which data should be included in astrochemistry models? Would laboratory data / theoretical work published in the astronomy literature also get published in the chemistry / physics literature? Is this level of accountability required? Where should we hold a single database? How would we maintain it? IUPAC validation?

What level of data accuracy is really required within the limitations of the models?

Junko Takahashi

 

2:30                Discussion – lead by Alan Luntz

to address: what do current experimental / theoretical results tell us about H2 formation under astronomically relevant conditions? How can we convert lab data to astronomical timescales effectively? How should we present lab techniques to astronomers in a form they can understand and interpret? What experiments are still required e.g. if H2 is formed in an excited state what kinds of gas phase reaction channels are more accessible with H2 vibrationally excited? What is the most relevant surface for H2 formation – bare grain or ice, and if so what do we need to look at in the laboratory?

2:30                Discussion – lead by Ewine van Dishoeck

to address: what do current experimental / theoretical results tell us about ice formation under astronomically relevant conditions? From the laboratory perspective we need to understand the nature of underlying grains and sublimation (ice formation) more effectively – how can astronomy help? What are the implications of physical attributes of ices? What effect do physical attributes have on astronomical data? How should we grow our ices / prepare our samples in the lab? What about grain – gas interactions BEFORE the ices are formed – should these also be addressed

to address: what do current experimental / theoretical results tell us about molecule formation under astronomically relevant conditions? How can we convert lab data to astronomical timescales effectively? How should we present lab techniques to astronomers in a form they can understand and interpret? What experiments are still required e.g. should all grains be charged, how do we overcome particle size effects, which reactions are the most relevant to study, i.e. which have the biggest effect on model? What is the most relevant surface– bare grain or ice, and if so what do we need to look at in the laboratory?
