Exo-Milankovitch Cycles. I. Orbits and Rotation States

The obliquity of the Earth, which controls our seasons, varies by only ∼2 5 over ∼40,000 years, and its eccentricity varies by only ∼0.05 over 100,000 years. Nonetheless, these small variations influence Earth's ice ages. For exoplanets, however, variations can be significantly larger. Previous...
