A Massive Hot-Jupiter Companion that Disfavors Giant Planet Formation beyond the Water-ice Line
We report evidence for a brown dwarf companion with mass $3{4}_{-11}^{+30}\,{M}_{{\rm{J}}}$ in the KELT-20 system, in which an ultrahot Jupiter transits an A2-type star. The companion’s properties are inferred from a joint analysis of astrometric accelerations and transit timing variations, and its...
