Chemical elements are pretty good history teachers! Today’s paper describes how chemical abundances can tell us about the history of where a planet formed.
The number of super-Earths with small semimajor axis appears to decrease with the mass of the host star. How can this be, if more massive stars have more massive protoplanetary disks and thus more material to build planets from? An icy dead zone may be the answer to this riddle!
Happy spooky season, folks! This is a story about a haunted protoplanetary disk…
In today’s episode, the star’s have been preparing some planets. But have they all been using the same recipe to form them? We will have to “taste” their compositions to find our winner!
The authors of today’s paper decided to take a less radical approach into investigating the trans-Neptunian objects. Maybe we don’t need Planet 9 after all?
Protoplanetary disks don’t exist in isolation; when young stars pass each other by, their gravitational encounter can disrupt, or maybe even kickstart, planet formation.
