R. S. OPHIUCHI: REDUCTION OF SPECTRA FROM THE 1958 OUTBURST.
Abstract
Spectra taken at the 1958 outburst of R. S. Ophiuchi have been reduced to units of ergs /sq cm/sec/A and are presented as a function of time for the first month and a half after maximum. The Balmer decrement was constant during the first 3 weeks and agreed well with that found at the 1933 event. The hydrogen lines appeared cut-off on the violet in the early days and an absorption line with velocity around 4000 km/sec was indicated. Many narrow (< or = 1A) absorption and emission lines were noted, mostly from < and > Fe. <0III>, <NII>, and <NeIII> were seen after about the 5th day. Intensities and half-widths are given for all the lines measured. (Author)
