J/A+A/605/A21       H2CO production in HD 163296              (Carney+, 2017)

Increased H2CO production in the outer disk around HD 163296. Carney M.T., Hogerheijde M.R., Loomis R.A., Salinas, V.N., Oberg K.I., Qi C., Wilner D.J. <Astron. Astrophys. 605, A21 (2017)> =2017A&A...605A..21C (SIMBAD/NED BibCode)
ADC_Keywords: YSOs ; Protostars Keywords: astrochemistry - protoplanetary disks - submillimeter: stars Abstract: We analyze the radial distribution of H2CO and C18O in the protoplanetary disk around HD 163296, a Herbig Ae type protostar, with the aim of determining possible formation scenarios of H2CO. By comparing the two molecules and the millimeter continuum, we investigate the relationship between the presence of H2CO and CO depletion in the disk. Description: The FITS files contain data cubes for H2CO(303-202), H2CO(322-221), H2CO(321-220), C18O(2-1), and a 2D image of the 1.3mm continuum. The observations were taken with the Atacama Large Millimeter/submillimeter Array (ALMA). The formaldehyde and 1.3mm continuum data have a spatial resolution of 0.5". The C18O(2-1) data is part of the ALMA Science Verification data set released for HD 163296, with an angular resolution of 0.8".
