Reliable Detections of Atmospheres on Rocky Exoplanets with Photometric JWST Phase Curves The prevalence of atmospheres on rocky planets is one of the major questions in exoplanet astronomy, but there are currently no published unambiguous detections of atmospheres on any rocky exoplanets....

"Reliable Detections of Atmospheres on Rocky Exoplanets with Photometric JWST Phase Curves" by Hammond et al., incl. @xoplanets.bsky.social @nichollsh.bsky.social @astrochloe.bsky.social @tgmeier.bsky.social @astrojake.bsky.social @astrolisadang.bsky.social @johannateske.bsky.social today on arXiv!

Did plate tectonics give rise to life? Groundbreaking new research could crack Earth's deepest mystery. Emerging evidence suggests that plate tectonics, or the recycling of Earth's crust, may have begun much earlier than previously thought — and may be a big reason that our planet harbors life.

Great article on plate tectonics and why it is important for life. They also mention our 2021 paper on LHS 3844 b and you might spot some quotes from me in it 👀 🌋

Artist's impression of the surface (as seen from space) of a rocky planet around the TRAPPIST-1 star, a red dwarf, which is seen in the distance. Another small exoplanet transits the face of the glowing red host star.

Habitable zone planets around M-dwarfs: do they end up as airless rocks or do they retain atmospheres? 🌥️🪨 Join us Thu 5 Dec @ 16:00 UTC on Zoom for a #RockyWorldsDiscussion with Joshua Krissansen–Totton talking about TRAPPIST-1, models, & more!

DPhil in Astrophysics Astrophysics DPhils (PhDs) can be observational, theoretical or in instrumentation and topics range from cosmology through to exoplanets, galaxies and transients, pulsars and high-energy astrophysics.

If you're looking to do a PhD (DPhil) in Astrophysics in the city of dreaming spires, check out our projects in Oxford Physics! I have one on exoplanet atmospheres, and another with Ray Pierrehumbert on technosignatures. Email questions. Apply before Jan 5th! www.physics.ox.ac.uk/study/postgr... 🔭

Our paper “Interior dynamics of super-Earth 55 Cancri e” just landed on arXiv!

We run 2D mantle convection models and find that large super-plumes can form on the dayside, which is covered by a magma ocean 🌋
