Junge Sternobjekte
Junge Sternobjekte (YSO) sind Sterne in ihren frühesten Entwicklungsstadien. So wie unser Sonnensystem einst als Wolke aus Staub und Gas begann, entstehen diese Objekte durch den Gravitationskollaps. Man kann sie sich als „Sternenbabys“ vorstellen, die von einer Scheibe aus Material umgeben sind, aus der Planeten entstehen. Diese Scheiben ähneln den Ringen des Saturn, jedoch in einem weitaus größeren Maßstab. YSOs stoßen oft Gasjets aus, während sie versuchen, sich zu stabilisieren und die Kernfusion zu zünden. Es ist eine entscheidende Phase, die über ihre Zukunft als Stern entscheidet.

Molecular emission in the disk around DM Tauri reveals complex chemical processes
Yesterday
Sterne | Junge Sternobjekte | PlanetenentstehuPlanets 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...

YesterdaySterne | Junge Sternobjekte | PlanetenentstehuA narrow ring of gas has been characterized around the young star HD 152384. Located at the dust sublimation radius, the ring likely formed from the collisions of rocky planetesimals, offering a new look at early planetary system evolution....
9. 10. 2026Sterne | Exoplaneten | Junge SternobjekteA new protoplanet candidate, EK Cha b, has been identified orbiting a young red dwarf star. Detected via carbon monoxide emissions and infrared data, the object shows signs of a circumplanetary disk, marking a key step in studying planet formation....

New models confirm these shadows and a spiral structure are evidence of the planet's gravitational influence on the surrounding dust....
26. 9. 2026Sterne | Exoplaneten | Junge SternobjekteNew mass measurements of the infant planets orbiting V1298 Tau reveal that planets b and e are likely gas giants. These findings, based on long-term radial velocity monitoring, suggest higher masses than previously estimated from transit timing observations....
