In this bite, we talk about observations of substructure in a young circumstellar debris disk. What can the formation of multiple debris dust rings tell us?
I received a giant planet for Christmas! Where did it come from? At what distance from its star did it form? I try to use the planet’s atmospheric composition to answer those questions, but Piso et al. point out this method may not be as straightforward as I would imagine.
The puzzling architecture of the Solar system has long been a headache for planetary dynamicists. An alternative model of the gas giants’ movements may shed new light on the issue.
It is commonly believed that Earth and meteorites reveal substantial differences. Today’s authors challenge this view based on their laboratory experiments.
Five young stars in one system — all the same age but at different stages of their evolution. What can they tell us?
Observing protoplanetary disks with ALMA yields astonishing information about structures in disks. Today’s astrobite presents and discusses a thrilling disk with an inner dust cavity, as well as gaps and rings. Moreover the gaseous disk extends to much larger radii in gas than the dusty disk and may possibly be evidence for radial drift and effects of planet formation.
