If J1249+36 was the companion of a white dwarf, the supernova could have left trace elements that polluted the L subdwarf's atmosphere. Conversely, globular clusters contain stars that all have similar compositional properties, so it may be possible to link the star to a home population that way.
If neither of those pan out, we may need to look to Milky Way's satellites, to determine whether this tiny, dim star is a stranger from outside galaxy, just winking howdy as it passes through. Discovery was presented at 224th Meeting of American Astronomical Society.
