Abstract

We compiled a near-infrared photometric and polarimetric catalog of $5{\times}9$ fields (${\sim}39^{\prime}{\times}69^{\prime}$) in the eastern side of the Large Magellanic Cloud (LMC). This catalog contains 9067 sources brighter than 16 mag in the J, H, and Ks bands, the polarization degree and position angle of each source. The photometric and polarimetric data were simultaneously obtained in J, H, and Ks bands using SIRPOL, an imaging polarimeter of the InfraRed Survey Facility (IRSF), in 2008 December and 2011 December. In this poster, we present a comparison between our results and those of Nakajima et al. (2007, PASJ, 59, 519) on the same sources in the 30 Doradus region in the LMC. We also discuss possible uncertainties in our polarimetric results when the Source Extractor is used to measure aperture photometry.
