How do you communicate with these people? Is there a big email that you're sending out to everybody to kind of say, point your telescopes here tonight? How do you organize this group of people to help with these observations?
Franck MarchisGUEST
So we used to do it by email, but then we quickly realized that it will not be durable.
Franck MarchisGUEST
So now we have a Slack channel, and we also have a website where people can see how to observe and what targets are observable from their location.
Franck MarchisGUEST
And this one, TOI-4465b, was definitely an interesting target because we were suspecting it was a Jupiter, a warm Jupiter.
Franck MarchisGUEST
So we have diagrams showing where it's located, what people can expect to see.
Franck MarchisGUEST
And then people start engaging with us and say, hey, we would like to observe it.

But why is it important to also have amateurs and lay people who are at telescopes, too, looking up at the sky?

Frank MarchisGUEST
You don't have access to telescope, you don't really understand the physics behind it, and, uh, and suddenly you see a tiny point in the sky getting brighter and brighter over time, and then this tiny point start displaying a coma, then a tail.

Could you talk a bit about the modern tools that we're using here in the 2020s to study comets and objects like them?
