Planetenentstehung

Planeten entstehen aus Staub und Gas, die in einer Scheibe um einen jungen Stern rotieren. Stellen Sie sich unser Sonnensystem wie einen riesigen Wirbel vor: Die Sonne steht im Zentrum, und Staubkörner kollidieren darum herum. Sie ballen sich wie Schneebälle zusammen, um größere Körper zu bilden. In Sonnennähe ist es heiß, daher entstanden dort Gesteinswelten wie die Erde. Weiter draußen in der Kälte sammelten sich Gas und Eis an und schufen Riesen wie Jupiter. Dieser Prozess dauert Millionen von Jahren und verwandelt chaotische Trümmer in ein geordnetes System von Umlaufbahnen.

Image: Molecular emission in the disk around DM Tauri reveals complex chemical processes
Planets emerge from the dense, flat regions of gas and dust known as protoplanetary disks that surround young stars. By investigating the chemical conditions in the disk around DM Tauri, researchers can better understand the environment that influences planetary evolution. This study focuses on the distribution of two specific molecular ions, N2H+ and DCO+, which serve as chemical markers for the conditions found in these distant rotating disks. To map these molecules, the team used the Ataca...

Image: High resolution imaging reveals double-peaked dust structure in the TW Hydrae disk
New observations of the TW Hydrae protoplanetary disk reveal a dust structure at 52 astronomical units that features a double-peaked shape. The dust moves according to local orbital rules, and the lack of gas signatures suggests no massive planet is present....

Image: Scattered light imaging reveals properties of the cat
Beta Pictoris shows its Cat's Tail in new visible light observations. The dust structure, likely formed by a collision between two objects as massive as Charon, contains highly porous organic material. Warping in the outer halo suggests ongoing planetary interaction....
