Analytical Formulas of Molecular Ion Abundances and N2H+ Ring in Protoplanetary Disks [PDF]
, 2015 We investigate the chemistry of ion molecules in protoplanetary disks, motivated by the detection of N$_2$H$^+$ ring around TW Hya. While the ring inner radius coincides with the CO snow line, it is not apparent why N$_2$H$^+$ is abundant outside the CO ...
