Abstract (from CDS):

We present Gaia DR2 2144465183642117888, a previously unknown, wide white dwarf companion to the HP Dra eclipsing binary system. This companion was discovered through the Backyard Worlds: Planet 9 citizen science collaboration. It has separation of 14.″4 on the sky from the central eclipsing pair, translating to a projected separation of ∼1140 au. We present a review of the orbit and physical parameters of all the components in this now triple system.
