Thank you 😊
Does planet formation (theory) count as planetary science? If so I'd like to be added please :)
This article is tremendous fun whilst hitting the main problems on the head - why we will never live on Mars.This article is tremendous fun whilst hitting the main problems on the head - why we will never live on Mars.

Mars does not have a magnetosphere. Any discussion of humans ever settling the red planet can stop right there, but of course it never does. Do you have a low-cost plan for, uh, creating a gigantic ac...
Moreover, mid plane dust to gas ratios in dust traffic jams are enhanced to beyond ~1, creating plausible conditions for the streaming instability. But more on that in part 2 of this work. Stay tuned... 4/4
However, in contrast to planar-aligning discs, traffic jams in polar discs 1) form faster (due to faster precession), 2) drift inwards, 3) and seem to persist even after alignment 3/
The mechanism is the same as with planar aligning discs (Aly+ 21), the difference in the precession profiles between gas and dust creates regions the headwind felt by dust is minimized, forming dust traffic jams 2/
It's paper day! arxiv.org/abs/2406.06971@becastro.bsky.social , and Cristiano Longarini , this work establishes the formation of dust traffic jams in polar-aligning circumbinary discs. 1/
We investigate the formation of dust traffic jams in polar-aligning circumbinary discs. We use 3D smoothed particle hydrodynamical simulations of both gas and dust to model an initially highly...

*waves* Hi Sarah! I thought I would do a thread on Cats In Ancient Egypt since that is a great ? and also, loads of cat lovers here. Meww-ve along and don't put all your eggs in one Bastet... lets gooo: To start...the ancient Egyptians DID worship cats AND they loved showing them off...1/?
