  • 16. arXiv:2011.12319 Chemically tracing the water snowline in protoplanetary disks with HCO+Authors: M. Leemker, M. L. R. van 't Hoff, L. Trapman, M. L. van Gelder, M. R. Hogerheijde, D. Ruíz-Rodríguez, E. F. van Dishoeck Abstract: …40 AU. Our analysis of ALMA observations of HCO+ J=3−2 is consistent with the water snowline located around 100 AU. The HCO+ abundance drops steeply around the water snowline, but dust and excitation can conceal the drop in HCO+ emission due to the water snowline. Therefore, locating the water snowline with HCO+ in Herbig disks is very difficult Astronomy and Astrophysics. Eu
