Among the stars mentioned in this new paper is 51 Ophiuchi, known in Orion's Arm as Gearhead. Apparently, the system's disk was not detected, but the presence of the brown dwarf companion was confirmed.
HD 158643 B
Separation = 0.118 ± 0.013 arcsecond = 14.8 +- 1.6 AU
Mass = 0.07 +0.01 -0.02 Sol
I also tried to revise the architecture of the star system but it was hell, so I'll just drop this panel and leave the rest to whoever's in charge of the article...
