Abstract (from CDS):

We present the discovery of 2MASS J13173072+4833343, a low-mass stellar companion to the ∼5.5 Gyr old white dwarf SDSS J131730.85+483332.8. This companion was discovered through the Backyard Worlds: Planet 9 citizen science collaboration. We obtained a near-infrared spectrum of the companion and determined a spectral type of M8.5. Using the cooling age of the white dwarf, we determined that the stellar companion has a mass of ${0.077}_{-0.017}^{+0.005}$M☉, or ${80.2}_{-1.8}^{+0.5}$MJup, near the substellar boundary.
