By combining a Serkowski-law interstellar polarization with four stellar polarization models, the authors show that UV spectropolarimetry can recover intrinsic stellar polarization where the interstellar signal is weakest.

abstract
Much interest has been generated recently by the ongoing MACHO, EROS and OGLE projects to identify gravitationally lensed stars from the Large Magellanic Cloud and Galactic bulge, and the positive identification of several events (Alcock et al, (1993), Aubourg et al, (1993) and Udalski et al, (1993)). The rate at which such events are found should provide considerable information about the distribution of the low mass compact objects, brown dwarfs etc. responsible for the lensing, and their relative importance as a component of the cosmological `dark matter'. We show measurement of the polarisation of starlight during these events can yield considerably more information about the lensing objects than was previously considered possible. Furthermore, the consideration of extended sources is shown to have a significant effect on the interpretation of the profiles and statistics of the events.

Analyzing Stellar and Interstellar Contributions to Polarization: Modeling Approaches for Hot Stars
By combining a Serkowski-law interstellar polarization with four stellar polarization models, the authors show that UV spectropolarimetry can recover intrinsic stellar polarization where the interstellar signal is weakest.
