Full Metal Sky
What do the atmospheres of ultra-hot Jupiters and 70s music have in common? A good deal of metal.
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.
Pebbly Planets
According to one theory of planet formation, the secret to forming massive planets is through itsy-bitsy, teeny-weeny pebbles of dust. In today’s astrobite, we explore what sort of planets these little pebbles could form.
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.
A very close planet that is way out of line
Transiting exoplanets generally orbit in the same plane, so how is this planet so misaligned in this multi-planet system?
The Planets in the Gaps
We’ve strongly suspected they’re there. A new method promises to prove it.
