Query: Nikishin systems on star-like sets: Ratio asymptotics of the associated
  multiple orthogonal polynomials, II   In this paper we continue the investigations initiated in \cite{LopLopstar}
on ratio asymptotics of multiple orthogonal polynomials and functions of the
second kind associated with Nikishin systems on star-like sets. We describe in
detail the limiting functions found in \cite{LopLopstar}, expressing them in
terms of certain conformal mappings defined on a compact Riemann surface of
genus zero. We also express the limiting values of the recurrence coefficients,
which are shown to be strictly positive, in terms of certain values of the
conformal mappings. As a consequence, the limits depend exclusively on the
location of the intervals determined by the supports of the measures that
generate the Nikishin system.
