Continuing our series on the historical interaction between Western astronomy and Indigenous communities, this post discusses ALMA and other observatories in Chile.
The absence of dusty circumplanetary disks around young giant planets suggests moonetesimals grow relatively quickly.
On the third day of Christmas the ALMA gave to me, 20 highly resolved protoplanetary disks!
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.
Planets form from protoplanetary disks. How they can be heavier on average than the disks is questioning our theories of planet formation.
A series of papers between two research groups, investigating the nature of an unusual distant galaxy.
