The Distribution of 870 µm Continuum, CO(3-2) and HCO+(4-3) Molecules Around TW HYA, Based on Science Verification Data from ATACAMA Large Millimeter/Submillimeter Array (ALMA), Band 7 Data

Abdulrahman Malawi, Dalal Al Ghamdi

Abstract


The study of the chemistry of protoplanetary disks has broad implication for our understanding of planet compositions and the availability of the conditions necessary for life. The science verification data from the Atacama Large Millimeter/submillimeter Array (ALMA) band 7 (345 GHz) observation of TW Hya, a classical T Tauri star, at lines of HCO+ (4-3) and CO (3-2) with a 1.5" angular and 0.2km/s spectral resolution was used for this study. CASA, the common astronomy software applications package was used for the data reduction, including, calibrating, cleaning and imaging of both spectral line and the continuum. The final dust, CO(3-2) and HCO+(4-3) images of the disk and the corresponding models are presented and discussed.
