HDS spectrum of nova V2659 Cyg (Nova Cyg 2014)
Listed in IVOA Registry (Virtual Observatory)
We report on high-dispersion spectroscopy results of a classical nova V2659 Cyg (Nova Cyg 2014) that are taken 33.05 days after the V-band maximum.
Description
The spectrum shows two distinct blueshifted absorption systems originating from H I, Fe II, Ca II, etc. The radial velocities of the absorption systems are -620km/s, and -1100 to -1500km/s.
The higher velocity component corresponds to the P-Cygni absorption features frequently observed in low-resolution spectra. Much larger numbers of absorption lines are identified at the lower velocity. These mainly originate from neutral or singly ionized Fe-peak elements (Fe I, Ti II, Cr II, etc.).

Based on the results of our spectroscopic observations, we discuss the structure of the ejecta of V2659 Cyg. We conclude that the low- and high-velocity components are likely to be produced by the outflow wind and the ballistic nova ejecta, respectively.
