I want to advertise quickly a paper first-authored by my soon-finishing PhD student Jesper Nielsen, on the formation of the so-called radius valley for small exoplanets. arxiv.org/abs/2502.10186 https://t.co/jjuehR0JEv25 Feb 2025 15:24 +0000at://did:plc:rrng4ooplvv4bhtfeuogbl7f/app.bsky.feed.post/3liz6b7dngc2xhttps://bsky.app/profile/astroandersj.bsky.social/post/3li62gplbgc2kPessimists sound clever.

Our conclusion is that Earth likely formed by a combination of pebble accretion, large impactors and a giant impact.
