Optical-IR echelle spectroscopy of NGC 6302

Echelle spectroscopy of [Si VI] 1.96 μm, [Mg VIII] 3.03 μm, and [Ar VI] 4.53 μm, using UKIRT+CGS4, shows the line pro les in PN NGC 6302 are singly peaked and unresolved even at R ∼ 20 000, with line widths less than 22 kms-1. A photoionized structure is evidenced by spatial and velocity stratificat...
