Dynamical Friction on extended perturbers
O. Esquivel, B. Fuchs
Following a wave-mechanical treatment we calculate the drag force exerted by an infinite homogeneous background of stars on a perturber as this makes its way through the system. We…
Can Massive Dark Haloes Destroy the Disks of Dwarf Galaxies?
B. Fuchs, O. Esquivel
Recent high-resolution simulations together with theoretical studies of the dynamical evolution of galactic disks have shown that contrary to wide-held beliefs a `live', dynamicall…
Dynamical friction force exerted on spherical bodies
O. Esquivel, B. Fuchs
We present a rigorous calculation of the dynamical friction force exerted on a spherical massive perturber moving through an infinite homogenous system of field stars. By calculati…
Jeans instability of a galactic disk embedded in a live dark halo
O. Esquivel, B. Fuchs
We investigate the Jeans instability of a galactic disk embedded in a dynamically responsive dark halo. It is shown that the disk-halo system becomes nominally Jeans unstable. On s…
