Planetary Cookie Doughs at High Angular Resolution
On the third day of Christmas the ALMA gave to me, 20 highly resolved protoplanetary disks!
How can you tell if a young planet is migrating?
It is difficult to tell if planets embedded in their natal protoplanetary disks are migrating closer to their stars. The authors of today’s paper devise a new observational signature to figure that out.
How can planets be heavier than the disks that formed them?
Planets form from protoplanetary disks. How they can be heavier on average than the disks is questioning our theories of planet formation.
The strange case of quiescent and dusty
A series of papers between two research groups, investigating the nature of an unusual distant galaxy.
Filling (Dust) Gaps in our Knowledge of Planet Formation
With the awesome power of ALMA, scientists have observed a variety of dust gaps in protoplanetary disks. In today’s astrobite, we explore how these gaps might be related to planet formation.
The Planets in the Gaps
We’ve strongly suspected they’re there. A new method promises to prove it.
