For the second part of the talk, Sid shifts focus to multi-dimensional effects. #PlanetsAre3D
Our observations show a lot of structures that we need to investigate and we can do that using 2D retrievals: cutting the atmosphere in leading/trailing terminator to disentangle the signals. We can also look at this temporally resolved where at different times on the orbit, we probe different parts of the #atmosphere.
Thanks to high-res we can break degeneracies between Fe and clouds.

#PlanetsAre3D is definitely one of the most used statements at #SEHR2023. 🧡
Well joke’s on me: I should toot in between to not lose it all… Quick summary of what I just deleted…#SEHR2023
Jayne continues with an overview of what matters: #Detections, #abundances, and #dynamics!
Linking back to the tough initial question: How accurate do we have to measure abundances for how many planets in order to address planet formation? 🤓
So it is not only about detecting species, but understand what they tell us ☺️
Interestingly, not only high-res can tell us about #PlanetsAre3D.

The first talk of #SEHR2023 is given by Jayne Birkby from the University of #Oxford on „High resolution #spectroscopy for the atmospheres of #exoplanets“.
Jayne‘s talk is a broad #overview of the field to set the background for everyone. My favourite hashtag makes an appearance already. #PlanetsAre3D ✨
And yes, these #atmospheres are complicated: dynamics, complicated #chemistry, #clouds, atmospheric structure, non-LTE effects,… you name it!
