  Electromagnetic and linear gravitational radiation do not solely propagate on
the null cone in 3+1 dimensions in curved spacetimes, contrary to their
well-known behavior in flat spacetime. Their additional propagation inside the
null cone is known as the tail effect. A compact body will produce a signal
whose tail will interact with its future worldline, thus producing a
tail-induced self-force. We present new results for the tail-induced scalar,
electromagnetic and gravitational self-force for a test mass in orbit around a
central mass, including effects from the internal structure of that body.
