I'm excited to announce that my first solo-author paper has been accepted at ApJ: arxiv.org/abs/2502.19394. I study the dependence of hot Jupiter circulation on both the temperature and wind initial conditions building upon Liu & Showman (2013), finding that the circulation of typical HJ is robust.

Our new Nature Geoscience paper led by Danica Adams is now published: www.nature.com/articles/s41... Water-rock chemistry released hydrogen and helped make early Mars habitable to microbial life. We'll be able to test this idea directly once we can study Mars rocks here on Earth.

Just finished reading Buhler 2024, a creative new idea to explain how a sea the size of the Mediterranean once formed on Mars because the atmosphere collapsed. Nice use of cartoons too #planetaryscience #Mars @bot.astronomy.blue signup agupubs.onlinelibrary.wiley.com/doi/10.1029/...
