In this paper we present the application of an evolution strategy to
the problem of detecting multi-planet transit events in photometric
time-data series. Planetary transits occur when a planet regularly
eclipses its host star, reducing stellar luminosity. The transit
method is amongst the most successful detection methods for exoplanets
and is presently performed by space telescope missions.
The goal of the presented algorithm is to find high quality fits of
multi-planet transit models to observational data, which is a challenging
computational task. In particular we present a method for
an effective objective function evaluation and show how the algorithm
can be implemented on graphics processing units. Results on
artificial test data with three artificial planets are reported.
