Schematic of episodic atmospheric collapse and regeneration through impacts for a tidally locked planet. A) The planet has a volatile rich atmosphere which redistributes heat from the day- to the
ReplicationBench evaluates AI agents on end-to-end astrophysics research paper replication. For each paper, we supply the manuscript, dataset, and execution metadata, and a complete set of author-written tasks. We evaluate
Maps of average lensing parameters of simulated microlensing events due to different BFFPs over the 2D space log10−log10. Here, Fi and Fw are fractions of simulated microlensing events due to
We show the total surface flooding for a given topography as a function of Mg/Si and FeO for a 1 M⊕ planet with Earth-like molar ratios (i.e., Fe/Mg, Ca/Mg, Al/Mg).
