Abstract:We have studied optical properties of interstellar dust around the Orion A molecular cloud to investigate the size distribution and the composition of dust grains. Orion A is one of the most studied molecular clouds in the solar vicinity (d ≃ 400 pc). In this paper, we used optical and near-infrared photometric data. The optical data were obtained by BV RI bands imaging observations. The near-infrared data consisting of JHK S bands were taken from 2MASS point source catalog. We produced some color excess maps … Show more
