2MASSW J0746425+200322: is the secondary a star or brown dwarf?

GIZIS J.E. and REID I.N.

Abstract (from CDS):

2MASSW J0746425+200322 is the first L dwarf system with a dynamical mass determination. It has been claimed that the system is young (<500 Myr) and that therefore the secondary is clearly substellar. We argue that the balance of evidence suggests the system is old; the secondary is likely either a star or a long-lived transition object.
