Hi there, Martin Schlecker from MPIA in Heidelberg. I'm a PhD student with Hubert Kla and Thomas Henning and I study exoplanet demographics using planet population synthesis. In the work I'm presenting, we studied the relations between inner super-Earth and outer-Chine planets that live in the same system. And we were wondering, is there a difference in the composition of a super-Earth when there is a cold tube in the system compared to when there is none? We found that indeed there is such a difference and it lies on the properties of the proto-planetary disk in which the planets have formed. In a nutshell, if you have a moderately massive disk, 100 Earth masses also. We see that primarily icy cores formed just beyond the Iceland. They migrate to detectable distances and we end up with systems of volatile rich super-Earths of low-buck density. No chines are formed. If you have on the other hand a rather massive disk, several hundreds of Earth masses are more. You can form planetary cores further in and then migrate inwards to become dry super-Earths. But the conditions are also right to form giant planets further out and they prevent icy core from migrating inwards. In this case we get high density super-Earths in the inner system plus a distant giant planet. From this follows a testable prediction. If you find an inner super-Earths with a high density, you are more likely to find a cold tube putter in the same system as well. If you want to learn more about the implications of this prediction, have a look at the full poster PDF and do make sure to check out the paper. And of course if you have any questions, feel free to drop me a message. Thanks for watching and I hope to see you around at the meeting.
