LAW 9 LSPM J0115+4702S. Law et al (2008) derive a distance of 18.7 +9.3/-3.6 Law2008
pc and a projected separation of 5.2 +2.9/-0.9 au. Estimated spectral
types are M4.5 and M5.
In addition to the companion detected with AstraLux, it can be noted
that 2MASS J01154885+4702259 has a very similar proper motion to the
star J01155017+4702023 at just 27" separation (Roser et al. 2010), XXX2010
which is itself a close binary (Law et al. 2008). Thus, this is a very Law2008
likely quadruple system. Jnn2012
