HST Spectroscopy of the Orion Nebula
Published online by Cambridge University Press: 25 May 2016
Abstract
From our recent Faint Object Spectrograph (FOS) observations of the Orion Nebula obtained with the Hubble Space Telescope, we present preliminary results that address the nitrogen abundance. The list of detected lines and their identifications included the first measurement of the N II] 2142 Å line in an H II region. This measurement in conjunction with [O II] 2471 Å permits a new assessment of the important N/O ratio in Orion. Unfortunately, the measurements of the N III] 1747-54 Å multiplet and the O III] 1660-66 Å multiplet have poor signal-to-noise, precluding another independent derivation of N/O.
