Query: Polarization in exoplanetary systems caused by transits, grazing
  transits, and starspots   We present results of numerical simulations of flux and linear polarization
variations in transiting exoplanetary systems, caused by the host star disk
symmetry breaking. We consider different configurations of planetary transits
depending on orbital parameters. Starspot contribution to the polarized signal
is also estimated. Applying the method to known systems and simulating
observational conditions, a number of targets is selected where transit
polarization effects could be detected. We investigate several principal
benefits of the transit polarimetry, particularly, for determining orbital
spatial orientation and distinguishing between grazing and near-grazing
planets. Simulations show that polarization parameters are also sensitive to
starspots, and they can be used to determine spot positions and sizes.
