After positive evaluation by an international team of experts, the Priority Programme (SPP 1385) “The First Ten Million Years of the Solar System” supported by the German Research Council (DFG) has now embarked on its second funding period with twelve new projects on board.
The investigations of the priority programme revolve crucially around material from small bodies like asteroids and comets, the point being that they have not evolved to the formation of a large planet but have remained at the level of small planets called planetesimals. “This means that they have preserved the unchanged relics of dust and rock composition on the way to larger planetary bodies,” says Prof. Trieloff. In this connection, the scientists are investigating sample material from meteorites and comets as well as interstellar material from which the first small bodies and planetesimals took shape. Isotopic dating is used to define more closely the span of time in which asteroids hundred of kilometres across achieved their present dimensions. In addition, the scientists are looking into the heating and the chemical and physical development of planetesimals.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
