A chemical map of the outbursting V883 Ori system: vertical and radial structures

We present the first results of a pilot program to conduct an Atacama Large Millimeter/submillimeter Array (ALMA) Band 6 (211-275 GHz) spectral line study young stellar objects (YSO) that are undergoing rapid accretion episodes, i.e. FU Ori (FUors). Here, we report on molecular emission observations FUor system, V883 Ori. In order image object with full coverage from ~0.5 arcsec map size ~30 arcsec, disc outflow scales, combine ALMA main array (the 12-m array) Compact (7-m and total power (TP) array. detect HCN, HCO$^{+}$, CH$_{3}$OH, SO, DCN, H$_{2}$CO emissions most these lines displaying complex kinematics. From PV diagrams, detected molecules probe Keplerian rotating in direction perpendicular large-scale previously $^{12}$CO $^{13}$CO lines. Additionally, HCN HCO$^{+}$ reveal kinematic signatures infall motion. The north is seen H$_{2}$CO, SO emissions. Interestingly, reveals pronounced inner depression or "hole" comparable radial extension estimated for CH$_{3}$OH 230 GHz continuum. integrated intensity distribution likely result optical depth effects, wherein optically thick nature continuum towards innermost parts can subtraction artifact final flux level.
