The o II recombination line abundance problem in planetary nebulae
We present new observations of O II recombination lines in ten bright plane-tary nebulae, along with spatially-resolved measurements of O II and [O III] in theRing nebula NGC 6720, to study the discrepancy between abundances derived fromO II recombination lines and those derived from collisionally-e...
