There is a paper linked on the article which says potential causes for the dust distribution are Kuiper belt object collisions and radiation pressure (I'm assuming from the sun?) pushing dust outward

> New data (Figure 3) at larger heliocentric distances show that the SDC-reported dust f l uxes, out to 55 au, remained higher than current models expected. Each of the three physical phenomena: optical properties and radiation pressure (Arnold et al. 2019); compositional variation between silicates and ice (Grigorieva et al. 2007); and a further reaching than currently identif i ed distribution of dust-producing bodies in the solar system (Fraser et al. 2023), may contribute to the data/model deviation.
