Description
In cosmological structure formation, objects ranging from compact binaries to satellite galaxies evolve on bound orbits while they interact gravitationally with the surrounding matter distribution. In this talk, I will present an analytic approach to the dynamical friction acting on circularly moving point masses in a gaseous medium. I will show how it can be extended to dark matter backgrounds and to eccentric orbits. Some astrophysical implications will also be discussed.
