Self-gravitating thin shells are dynamically unstable on all angular scales
Tristan Pitre, Berend Schneider, Eric Poisson
We establish the dynamical instability of a static, spherically symmetric, and infinitesimally thin shell in general relativity. The shell is made up of a perfect fluid with a baro…

Impact of nonlinearities on relativistic dynamical tides in compact binary inspirals
Tristan Pitre, Eric Poisson
The tidal deformation of a neutron star in a binary inspiral driven by the emission of gravitational waves affects the orbital dynamics and produces a measurable modulation of the…

Tidally induced multipole moments of a charged material body
Victoria Leaker, Tristan Pitre, Eric Poisson
We define and calculate the mass multipole moments of a material body of mass and electric charge tidally deformed by a particle of mass and charge plac…
