Jordan et al. (2020) found a faint source separated from HATS-38 by 6 arcseconds (∼2,100 AUs), too faint and too distant from the star to be responsible for the transit signal and compatible with a low-mass M dwarf (m = 0.09 MSol). However it could also be an extragalactic source, either an earlier M dwarf star in the background of HATS-38 or a foreground brown dwarf.
