Harmonic-decomposition approach to dynamical friction for eccentric orbits
Gali Eytan, Vincent Desjacques, Yonadav Barry Ginat
Compact objects evolving in an astrophysical environment experience a gravitational drag force known as dynamical friction. We present a multipole-frequency decomposition to evalua…

Acoustic wake in an isothermal profile: dynamical friction and gravitational wave emission
Gali Eytan, Vincent Desjacques, Robin Buehler
We consider the motion of a circularly-moving perturber in a self-gravitating, collisional system with spherically symmetric density profile. We concentrate on the singular isother…
