Three-dimensional dust mapping in the Orion Complex, combining Gaia-TGAS, 2MASS, and WISE

Abstract

We present a map of the three-dimensional (3D) distribution of dust in the Orion complex. Orion is the closest site of high-mass star formation, making it an excellent laboratory for studying the interstellar medium and star formation. We use data from the Gaia-TGAS catalogue combined with photometry from 2MASS and WISE to get the distances and extinctions of individual stars in the vicinity of the Orion complex. We adopt the non-parametric method of Rezaei Kh. et al. (2017) to infer the probability distribution function of the dust densities at arbitrary points throughout the region. We map the dust distribution towards different parts of the Orion complex and find the distance and depth of the cloud compatible with other recent works which show the ability of the method to be applicable on the local molecular clouds to map their 3D dust distribution. We also demonstrate the danger of only using colours of stars to derive their extinctions without considering further physical constraints like the colour-magnitude diagram (CMD).
