Phase 3 – Working Group 6 “Complex Dust”
Goal of WG6 “Complex Dust”
Dust and solid bodies are a most important component of all planets and planetary systems from their formation to their later evolution states. Knowing better the properties and the evolution of dust particles and solid surfaces of larger bodies is therefore a key requirement for the investigation and understanding of planetary systems. However, solids are extremely diverse and undergo many complex processes and therefore many important aspects of solids are not well understood and often only considered in a highly oversimplified manner.
This working group aims for a strengthening of the cross-disciplinary discussion and collaboration between all the NCCR researchers working on dust and solid bodies. The goal is to combine the existing knowledge from different diciplines for more sophisticated interpretations of our measurements and model results.
We are particularly interested to learn about the following topics from NCCR experts working on:
- laboratory analysis of the chemical and physical properties of meteorites and micro-meteorites
- in-situ measurements of interstellar and interplanetary dust with spacecrafts experiments
- laboratory measurements of the reflectivity of analogues for surfaces of solid bodies in the solar system
- laboratory experiments and theoretical studies of icy particles
- micro-gravity experiments of the hydrodynamical properties of dust suspended in gas
- numerical modelling of the dust hydrodynamics in protoplanetary disks
- observational studies of the scattered and emitted radiation from dust in circumstellar disks

Understanding the properties and evolution of dust and surfaces of solid bodies in planetary systems
one day WORK SHOP, Monday Nov. 21, 2022, 9.30 am to 5.00 pm, plus dinner; ETH Hoenggerberg
Organizing committee: Nicola Allen, Holly Capelo, Niels Ligterink, My Riebe, Hans Martin Schmid
According to our Kick-Off zoom discussions from September 2022, we would like to meet in a face-to-face meeting to get to know each other better and to learn from the knowledge about dust and surfaces of solid bodies in planetary system from different disciplines. The goal is to find well defined questions for scientific interactions and collaborations which could benefit from the knowledge of people working in different fields.
The work shop consists of an introductory session with solicited overview talks, followed by 3 sessions, each with first a few short (5 min) “rapid fire learning” talks followed by about 15 minutes of plenary discussions and 15 minutes of ad-hoc discussions within groups. During these discussions, we will start with setting up a “word map” for WG6, which will then serve as basis for the final discussions about possible science collaborations. At the end, we will try to formulate action items with goals and responsibilities.
Below is a little guide for the rapid fire learning speakers:
Rapid fire learning (RFL) works a little bit different than the scientific presentations most of us are used to. RFL presentations are short (5 minutes) and serve as catalyst for the discussion, to which most time is allocated in the session. The aim is to have as much interaction as possible, rather than a one-way flow of information. To help with making the presentation, we have number of pointers:
– Make your presentation short (~5 slides), as it has to fit in 5 minutes.
– Keep your introduction / context short and concise (1 slide)
– It is best to focus on the highlights or key concepts of your work
– However, it is ok to make slides information-dense and include information about the details (e.g., an equation, experimental technique, etc). You don’t have to cover the details during your presentation, but it may be useful for the discussion. Unlike a regular presentation, where you want to keep the attention of the audience for 30-45 min. and therefore use “clean” slides that are not saturated with information, in RFL slides it is ok to bombard the audience with info.
– You can use the presentation to point out some ideas for future research directions / experiments / open questions / collaborations / etc. This will help start the discussion.
– No problem to have a few back-up slides ready, but also be prepared to, for example, draw something on the blackboard.
