Rough Estimates of Solar System Gravitomagnetic Effects in Post-Newtonian Gravity

open access: yesUniverse
In order to properly describe the gravity interactions, including the mass currents, in gravitomagnetism, we construct four Maxwell-type gravitational equations that are shown to be analogs of the Maxwell equations in electromagnetism.

Do Super-puffs Defy Core Accretion? Population-wide Interior Structure Constraints

open access: yesThe Astrophysical Journal
Sub-Saturn mass planets with extremely low bulk densities ( ρ  ≲ 0.3 g cm ^−3 ), or “super-puffs,” are one of the most interesting and least understood populations of exoplanets.
