Dynamics and control of electromagnetic satellite formations [PDF]

open access: yes2006 American Control Conference, 2006
Satellite formation flying is an enabling technology for many space missions, especially for space based telescopes. Electromagnetic formation flying (EMFF) is a novel concept that uses superconducting electromagnetic coils to provide forces and torques between different satellites in a formation.

Formation of Giant Planet Satellites [PDF]

open access: yesThe Astrophysical Journal, 2020
Abstract Recent analyses have shown that the concluding stages of giant planet formation are accompanied by the development of a large-scale meridional flow of gas inside the planetary Hill sphere. This circulation feeds a circumplanetary disk that viscously expels gaseous material back into the parent nebula, maintaining the system in a
