The Planets Team has regular Journal Clubs. Everyone is very welcome to join!
Here you can find information regarding the papers to be discussed in the next sessions, as well as the works already presented.

Some tips for your presentation:

• The goal of these presentations is to quickly share a recent paper or result that is relevant for our fields and have a quick discussion about its main content.
• Focus on the most important aspect you want to show or discuss, it can be a new method, a controversial result, an open question, the paper’s shortcomings or something else.
• Don’t be afraid of not going over data/models that are not very relevant in the scope of the presentation.
• Feel free to use different formats for your presentations. Slides and more dynamic visual representations can be easier to follow for the audience than paper format.
• Give some context to the paper, especially if the authors have failed to acknowledge that what they are saying is controversial.
• Simple visual representations of complex ideas, pathways, or techniques to help your audience better understand the information. Sometimes it’s better to “sacrifice” part of the paper in order to get a more simple message clearly through.

When: Every two weeks – Tuesdays following the Planets Team Meetings (~15h30)
Agenda: Two presentations (5 min + 5-10 min discussion each)
Duration: 20-30 min
Connection: Zoom link – Planets team meetings

Paper library: https://ui.adsabs.harvard.edu/public-libraries/J3l3Q3nHSHadqExctiZ_Bg
If you find an interesting paper but you don’t have time to read and present it, please add it to our library, so someone else can present it, or use it in case you need an idea for your next presentation.
Please let us know if you don’t have permission to add papers to the library!

 

Next Speakers (2024/2025):
Volunteers are always welcome! If you find a cool paper, feel free to present!!
Order is not absolutely mandatory, can be changed upon request.
