Revealing The Shiny Nature Of Lava Worlds: Small Planet Phase Curves With TESS
[astro-ph.EP] Recent thermal emission observations suggest that `lava worlds’–Earth-sized exoplanets hot enough to melt their silicate surfaces–have atmospheres on a population-level.

Thermal Evolution of Lava Planets Across System Ages: Predictions for Hell of a Survey
[astro-ph.EP] Ultra-short-period (USP) rocky exoplanets can have dayside temperatures high enough to maintain permanent magma oceans, sitting at the intersection of interior geophysics and atmospheric chemistry. Coupled feedbacks between the […]

Coupled Orbital And Interior Structure Evolution Of Lava Planets
Lava planets likely did not form in their current orbits, instead migrating inward via orbital decay, which influenced the evolution of their magma oceans.

An Earth-Sized Planet In A 5.4h Orbit Around A Nearby K Dwarf
We present the discovery and confirmation of the ultra-short period (USP) planet TOI-2431 b orbiting a nearby (d∼36 pc) late K star (Teff = 4109±28K) using observations from the Transiting […]
