 Speaker: Huize Wang

 Huize will lead a ClimaTea discussion on the some recently discovered Earth-sized exoplanets orbiting TRAPPIST-1 and their possible atmosphere compositions.  
In the discussion, Huize will lead us through the following key points:

- Transit observations provide critical information that leads to the **discovery of the TRAPPIST-1 planets**.
- Transit spectroscopy helps us to **understand the atmosphere compositions**. For example, it rules out the possibility to have cloud-free hydrogen-dominated atmospheres for some planets.
- Certain aspects of **climate states and habitability** of these exoplanets can be inferred from this observation, although caveats and limitations exist.
