Title: Astro-chemical modeling to Planck cold clumps G224.4-0.6
Abstract: Offsets of molecular line emission peaks from continuum peaks are very common but frequently difficult to explain with a single spherical cloud chemical model. We propose that the spatial projection effects of an irregular three dimensional (3D) cloud structure can be a solution which has the potential to explain such asymmetrical distributions of chemicals in many other molecular clouds. I will talk about how to successfully apply the idea to the Planck cold clump G224.4-0.6 by approximating it with four individual cloud cores whose chemical patterns overlap with each other to reproduce the observed molecular line maps.
