Contrasting C/O Ratios in Uranus and Neptune From Disequilibrium Chemistry: A Clue To Distinct Evolutionary Pathways?
[astro-ph.EP] The formation of Uranus and Neptune remains poorly constrained largely due to uncertain deep elemental abundances. Carbon monoxide (CO), a disequilibrium species in the upper troposphere, provides an indirect […]

Neptune’s Obliquity Was Likely Engendered By Triton’s Tidal Evolution
Neptune’s present axial tilt of approximately 28 deg. with respect to its orbital plane can be explained by collisions that its primordial core may have experienced with surrounding planetary embryos […]
