NSVS 10653195 is a double-line detached eclipsing binary star found in
2007 by te{coughlin2007} among the NSVS periodic variable stars. The
first analysis of the optical VRI light curves by te{coughlin2007} show
that this binary could be composed by two low mass stars. Other authors
analyzed new optical light curves for this system, obtaining some
parameters, like the mass ratio (q) from the light curves, given the
absence of radial velocity (RV) measurements.This procedure is
unreliable in the case of detached eclipsing binaries, leading to large
uncertainties in the physical parameters of the system. We obtained new
IR light curves and radial velocity measurements to characterize the
physical properties of this system, in particular masses and radii. In
addition, calibrated optical BVRI photometry was obtained to fully
constrain the effective temperature of the two components of this
system. The modelling of this system with the ěrb|rvfit| and
Phoebe package show that the mass ratio q is very different of
previously published values, showing that the secondary component, as
defined by the light curve, is slightly more massive than the primary.
We are currently finishing the modelling of this interesting eclipsing
system.
