Abstract: An extreme mass ratio inspiral consists of two parts: adiabatic inspiral and plunge. The plunge trajectory is quite universal (independent of initial conditions). We write an expression for its solution in closed-form and for the emitted universal waveform. In particular we extract an expression for the universal black-hole ringdown amplitudes, which reduces to solving certain ordinary (radial) differential equations in the Schwarzschild background.
