The formation of stars and their planetary systems are among the key questions in science.
Only by addressing these fundamental questions, we can hope to unravel whether solar systems like ours are common and how many Earth-like planets our Galaxy may harbor. In recent years
substantial progress in this direction has been achieved thanks to a powerful combination
of high-resolution, high-sensitivity observations aided by detailed theoretical modeling
and laboratory studies. The composition and properties of exoplanetary atmospheres are now
becoming routinely accessible thanks to the high-resolution coronographic or spectroscopic
observations from the ground and space. The diversity of observed exoplanets and their
atmospheric composition suggests a tight link between exoplanets and the properties of their
pre-natal environments, protoplanetary disks. From the optical to the (sub-)millimeter,
observations provide strong evidence for the ongoing planet formation and the presence of
planets in their pre-natal environments, protoplanetary disks.
The goal of the AG 2019 splinter meeting entitled "From protoplanetary disks to exoplanets
- the story of their formation" is to bring together the German astrophysical community studying
exoplanets, planet formation, and protoplanetary disks. Beside summarizing the status of the
field in several lectures and presenting the latest, most interesting results, the organizers
hope to stir the discussions and exchange of ideas within our diverse research field.
Key scientific topics include (but are not limited to):
- What are the physics and chemistry of planet-forming disks? How do these disks evolve?
- What are the conditions under which planets form?
- Which processes shape the properties of planets and their atmospheric compositions?
- Is our solar system unique or common?
- Which processes do we have to test (and exclude) in order to identify the imprints of planets on disks?
- Might other processes (such as magnetic fields) solve the chicken-and-egg problem of planet formation?
Invited speakers:
- Barbara Ercolano: "The evolution and dispersal of protoplanetary
disks" (LMU Munich, DE) - Geoffroy Lesur: "The structure and evolution of protoplanetary disks"
(Uni. Grenoble, FR) - Wilhelm Kley: "Planet migration in protoplanetary disks" (Uni. Tuebingen, DE)
- Kees Dullemond: "Theory and observations of dust in protoplanetary discs" (ITA/ZAH Heidelberg)
- Mark Wyatt: "Debris disks" (IoA, Cambride, UK)
