Abstract. We present a mathematically rigorous expression for the residence-time
distribution of a periodically forced Brownian particle in a bistable
potential. For a broad range of forcing frequencies and amplitudes, the
distribution is close to a periodically modulated exponential one.
Remarkably, the periodic modulation is governed by a universal function,
depending on a single parameter related to the forcing period. The
behaviour of the distribution and its moments is analysed, in particular in
the low- and high-frequency limits.
