Three accelerating stars yield one stellar companion at 166 AU, one 45 Jupiter-mass object at ~18 AU, and one 9.5 Jupiter-mass object at 6.4 AU that is 65% likely to be a planet.

Resolves six speculative companions into one giant planet, one eccentric brown dwarf, two low-mass stars, and two stars with no detectable companions.
Tentative evidence for a super-Jupiter at 15-100 AU or brown dwarf at 20-170 AU in 51 Pegasi from RV curvature, but the signal is likely driven by Lick/Hamilton instrument drift.
Refined ephemeris for WASP-18 b with no support found for proposed companion WASP-18 c from combined transit timing and RV analysis.
Collates archival stellar activity and rotation data for potential HWO targets, finding measurements for at least 70% of high-interest systems but activity cycles for fewer than 20%.
