Search for spectral features in the gamma-ray flux from the Sun.

Dark matter particles from the galactic halo could interact with solar nuclei and be captured by the Sun either in external orbits or in its core. In both scenarios, a gamma-ray signal from the Sun is expected, with photons originating directly from annihilating pairs of dark-matter particles or from their annihilation into long-lived intermediate states which in turn decay into photons. In this contribution we will present the results of a dedicated analysis using a 10-years sample of photons collected by the Fermi LAT, searching for dark matter signatures in the gamma-ray energy spectrum towards the Sun.
