Gas-induced friction and diffusion of rigid rotors
We derive the Boltzmann equation for the rotranslational dynamics of an arbitrary convex
rigid body in a rarefied gas. It yields as a limiting case the Fokker-Planck equation …

Systematics and consequences of comet nucleus outgassing torques
D Jewitt - The Astronomical Journal, 2021 - iopscience.iop.org
Anisotropic outgassing from comets exerts a torque sufficient to rapidly change the angular
momentum of the nucleus, potentially leading to rotational instability. Here, we use empirical …

Nongravitational effects of cometary activity
Nongravitational forces induced by sublimation of volatiles affect the rotational and orbital
dynamics of comets. In addition to contributing to the improvement of ephemerides and of …

Rapid variations of dust colour in comet 41P/Tuttle–Giacobini–Kresák
We monitor the inner coma of comet 41P/Tuttle–Giacobini–Kresák searching for variations of
its colour. Fast changes in colour of the comet 41P/Tuttle–Giacobini–Kresák provide …
