Extreme Geomagnetic Storm On Early Earth Induced by Corotating Interaction Regions from the Young Sun
Recent multiwavelength observations of young solar analogs suggest that the young Sun in the first 600 Myr was a magnetically active star that produced an X-ray and Extreme-UV (EUV) bright […]

The Open-Source Photochem Code: A General Chemical and Climate Model for Interpreting (Exo)Planet Observations
With the launch of the James Webb Space Telescope, we are firmly in the era of exoplanet atmosphere characterization. Understanding exoplanet spectra requires atmospheric chemical and climate models that span […]

Terrestrial Planet Formation From Two Source Reservoirs
This work describes new dynamical simulations of terrestrial planet formation. The simulations started at the protoplanetary disk stage, when planetesimals formed and accreted into protoplanets, and continued past the late […]
