Concluding remarks from Ignas Snellen, chair of SOC and director of the Leiden Observatory.
A great conference, well organised for such a massive turnout of ~800 #exoplanet astronomers.
A lot to digest here, especially regarding #JWST results. #Exoplanets5

Caught a long-term collaborator Prof. Jenkins next to his poster on LTT9779 b, with evidence for silicate and titanium clouds.

Conferences inspire.
But not only in the obvious, tey inspire because scientists readily admit their failures.
When hundreds of scientists express how they have failed in what you have struggled to do, too, it inspires.
It becomes clear that you did not fail because you are bad at your job, but because nature doesn't yield her secrets easily.
It means you are not falling behind.
That motivates trying even harder until breakthroughs eventually happen.
And they will happen.

Today's the final day of #exoplanets5! It's been a great week - Leiden has been swamped with nearly a thousand exoplanetary astronomers. It's been both extremely rewarding & simultaneously draining to catch up with so many old colleagues and friends, plus make a few new ones.

What we have learned in #exoplanets5?
Most rocky exoplanets are bare rocks without atmospheres.
Astronomers hardly ever agree on anything.
More data is always needed.

A new tool for estimating #exoplanet radii and masses, if only one of them is known.
The tools applies the assumption that small #exoplanets have three compositional modes: fully rocky, water worlds, and mini-Neptunes with thick gaseous envelopes.

Another great poster by Cortés-Zuleta et al. about multiwavelength caracterisation of #planets. #exoplanets5
It is great because it demonstrates beyond any doubt that my hypothesis, that AD Leo is orbited by a gaseous #planet in spin-orbit resonance, is definitely wrong.
This is achieved with infrared radial velocities.
To be shown wrong is to learn, so it is great!

A cheeky poster in #exoplanets5 by me!
Cheeky because it is really about mapping active regions on young and active #stars.
But we do the mapping by using exoplanets as tools, and the results enable studying how active the stars are in the plane of the planetary system.
Our example target is Kepler-411, a well-know host of a densely packed planetary system.
