Dynamical Duo: An Updated Understanding of the Orbits of the Two Giant Planets in the HD 45354 System
In today’s paper, the authors take another look at the HD 45354 planetary system, and come to new conclusions about the orbit of the two gas giants within!
Knock, knock. Who’s there? A free floating planet!
Not that long ago, in a system not too far away, a free-floating planet pays a visit… to HD 106906, a binary star system with an exoplanet and a debris disk!
Diffusion and depletion of carbon monoxide in disks
Where is the missing carbon monoxide in protoplanetary disks? Today’s paper suggests that it might have something to do with turbulent mixing in disks as well as the physics of condensation.
We don’t need Planet 9!
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?
Understanding the surprising narrowness of eccentric debris belts
Some extrasolar debris belts are not just eccentric but also surprisingly narrow. What processes can influence the width of debris belts?
