V339 Delphini
Date

The early temporal development of the classical nova V339 Delphini was observed using FORCAST grisms, which provide coverage from 5–40 μm at low spectral resolution. These data revealed a full suite of hydrogen recombination lines, the analysis of which indicated that the ejecta were still at very high density (ne > 1013 cm-3) and that the hydrogen lines were optically thick.
