The IceCube neutrino observatory--installed in the Antarctic ice--is the largest neutrino telescope to date. It consists of 5,160 photomultiplier-tubes spread among 86 vertical strings making a total detector volume of more than a cubic kilometer. IceCube detects neutrinos via Cherenkov light emitted by charged relativistic particles produced when a neutrino interacts in or near the detector. The detector is particularly sensitive to high-energy neutrinos of due to its size and photosensor spacing. In this analysis we search for dark matter that annihilates into a metastable mediator that subsequently decays into Standard Model particles. These models yield an enhanced high-energy neutrino flux from dark matter annihilation inside the Sun compared to models without a mediator. Signals produceddirectly inside the solar plasma are subject to strong attenuation. Mediators produced by secluded dark matter can however escape the Sun and avoid any such attenuation. We present the results of an analysis of six years of IceCube data looking for dark matter in the Sun for dark matter masses ranging from 200 GeV to 75 TeV.
