# Extinction and the Dimming of KIC 8462852

Huan Y. A. Meng, George Rieke, Franky Dubois et al., 2017. _The Astrophysical Journal 847(2), 131_.

Swift, Spitzer and ground photometry from October 2015 to December 2016 show the star still fading, by about 22 mmag per year in the ultraviolet and 5 mmag per year at 3.6 to 4.5 microns. The wavelength dependence is less steep than interstellar extinction, pointing to circumstellar material.

## What it's used for here

The colour of the secular fade, and the case that it is circumstellar dust.
