Futureproof with Jonathan McCrea
What is ‘Forensic Botany’?

You can have an eclipsing binary star, so these two star systems, and then a planet orbiting that.

Futureproof with Jonathan McCrea
What is ‘Forensic Botany’?

It's super cool.

Futureproof with Jonathan McCrea
What is ‘Forensic Botany’?

And, you know, very recently kind of discovered.

Futureproof with Jonathan McCrea
What is ‘Forensic Botany’?

So this is what this paper did.

Futureproof with Jonathan McCrea
What is ‘Forensic Botany’?

They found 27 new candidate planets that may be orbiting these stars.

Futureproof with Jonathan McCrea
What is ‘Forensic Botany’?

And, you know, these binary star systems are, you know, half of the stars that we see are these eclipsing binary stars.

Futureproof with Jonathan McCrea
What is ‘Forensic Botany’?

No, yeah, yeah.

Futureproof with Jonathan McCrea
What is ‘Forensic Botany’?

That would be really cool.

Futureproof with Jonathan McCrea
What is ‘Forensic Botany’?

Yeah, I mean, some of them could have these crazy orbits that we don't necessarily fully know yet, right?

Futureproof with Jonathan McCrea
What is ‘Forensic Botany’?

We can't see them.

Futureproof with Jonathan McCrea
What is ‘Forensic Botany’?

So we have to try to identify these different kind of methods to seeing them.

Futureproof with Jonathan McCrea
What is ‘Forensic Botany’?

But if you think you're kind of all orbiting some center of mass in the middle of those two stars, you can also have planets that are orbiting one star and then the other star is there and all these different orientations.

Futureproof with Jonathan McCrea
What is ‘Forensic Botany’?

But again, that makes it really hard to see because we can't just see these exoplanets.

Futureproof with Jonathan McCrea
What is ‘Forensic Botany’?

They're so, so faint.

Futureproof with Jonathan McCrea
What is ‘Forensic Botany’?

And so we have to do kind of really smart techniques like this gravitational thing of seeing how this gravitational pull of these planets have an impact on the star.

Futureproof with Jonathan McCrea
What is ‘Forensic Botany’?

And then we can look at the stars and see their tiny wobbles in those stars.

Futureproof with Jonathan McCrea
What is ‘Forensic Botany’?

And then we can infer, oh, maybe there's planets orbiting.
